How Long Does a Key Fob Battery Last?
In order to get into a modern car, you will usually have to have the key fob that comes with the car. These key fob can do everything from unlocking the doors of the car to remote starting, in some cases. These fob are powered by a small flat key fob battery. Just like any other battery, eventually, the key fob battery will have to be replaced in order to keep the key fob functional. Every time that a driver wants to use their key fob, the battery will have to produce the electricity that is needed to power it. A key fob battery will usually last around three to four years before it will need to be replaced. Not having a fully functional key fob can lead to a lot of frustration and stress. In some cases, it will be impossible for a person to get into their car without a working key fob. When the time comes to get a new battery, you will have to take some time to research exactly what you need. By getting an idea of what is needed, you will be able to find the right battery in no time at all.
Usually, getting the battery out of a key fob can pose a bit of a problem for an inexperienced car owner. Some key fob will snap apart, while others will have a screw that will need to be taken out. Attempting to do this on your own may cause you to damage the key fob, which will cost you even more money to fix. Many of the key fob out there are quite expensive due to how high tech they are.
When your key fob battery is bad, here are some of the things that you will start to notice when your key fob battery is going bad:
- The car will not unlock
- It is taking a lot more effort to get the key fob to work
- The buttons on the key fob will only work on occasion
By noticing the signs that your key fob is giving you, it will be easy to replace the battery and restore its functionality. Make sure that a high-quality replacement battery is replaced correctly or just have an experienced mechanic inspect and replace the key fob battery for you.
Key fob Won't Start Engine
Most late model cars and light trucks use a Start button instead of an ignition key to start the engine. The Start button must receive a coded signal from a Smart Key fob before it will start the engine when you press the button. If nothing happens, it may mean one of several things:
The battery inside your key fob is dead or too low to send a good signal to the key less entry system and needs to be replaced.
The key fob itself is defective. This will require replacing the fob with a new one, either from a car dealer or an aftermarket fob (which will have to be reprogrammed to your vehicle by a car dealer or certified locksmith).
You are not pressing down on the brake pedal, or the brake pedal position switch is defective, or the transmission gear selector is not in Park. On vehicles with manual transmissions, you have to fully depress the clutch pedal before the engine will start.
There is a problem with the key less entry system or Start button. The key less entry system may not be reading the signal from the key fob because of an antenna or wiring fault, or the Start button may not be generating a signal when you press it down. These conditions will require further diagnosis and will likely require having your vehicle towed to a service facility or car dealer for repairs.
Your car battery is extremely low or dead. This may require a jump start before your engine will crank and start.
DEAD KEY FOB? YOU CAN STILL UNLOCK AND START YOUR CAR
If you’ve just found yourself locked out of your car with a dead key fob, we may be able to get you going.
Remote key fob are great until they fail. When they do, you may not be able to enter the car. Then, if you get inside, getting the car started can be foiled by a dead START button. We’ve got loads of solutions here, so find the one that most closely fits your scenario:
Swap the Battery
If your remote key fob has given up the ghost in the parking lot of a shopping centre, you may be in luck. The battery may have failed, and getting it to work again might be as easy as replacing it.
To access the battery, you’ll have to open the fob. Typically, you have to use a coin or a small screwdriver to pry the battery cover open. The battery will look like a silver button. Look for the numbers on the battery and match those to a replacement battery.
Unlock the Door Remotely
Many manufacturers have remote door unlock services that can get you inside the car if your key fob is disabled, or if you’ve locked your keys inside. If your car doesn’t have an advanced remote unlocking system, roadside assistance can still get you inside. All of these services require that you have set them up ahead of time, and generally require a PIN.
If you don’t have one of the services described above, you can still try calling Roadside Assistance. The number is typically posted on the side windows and in the owner’s manual.
Unlock the Door Manually
Barring that, try holding your dead fob up against the driver’s door handle and pulling. Sometimes there’s just enough juice in the battery to unlock it at a close distance.
If that fails, look closely at the fob. If it has a leather jacket on it, remove it. Almost all automakers hide a small mechanical key inside the fob. There is usually a small catch that allows the spare key to pop out. If you can expose the little mechanical key, you can then insert it into the lock opening in the driver’s door, and you’re in.
How To Start a Car With a Dead Key Fob
Once you’re inside, getting the car started is actually pretty easy. Automakers know that your key less ignition may need to work if the fob dies, and the system has been designed to work even with a non-functioning remote. Some cars are equipped with a means of starting the car manually, and some have a backup built into the key fob that works without a key.
Even if your car has key less entry, you may not have noticed that there’s actually a key slot somewhere on the steering column. Mazda vehicles, for example, are equipped this way. The “switch” you turn is actually a plastic cap that pops off, revealing a key slot underneath.
If your key less entry works with a START button and there’s no mechanical key slot, there’s still a way to start the car. Use the key fob to push the START button. Some manufacturers have a backup system that allows this method to work if the key fob battery is dead.
What Does the Key Fob Battery Low Warning Light Mean?
Key fob has made life much easier for drivers. Short for “finger operated button”, key fob allows us to unlock all of the doors at once without having to fiddle with the keys.
Some cars are so sophisticated that they can be unlocked just by carrying the key fob with you as you approach the car. Unfortunately, the fob use batteries which eventually run out of power. If your key fob battery went completely dead, you wouldn’t be able to start the car and could end up stranded somewhere. To prevent this from happening, there is a warning light on the dashboard that indicates when the battery should be replaced in the fob.
What the key fob battery low warning light means
When the key is in use, the computer monitors the output voltage of the fob’s battery. Once the voltage gets to a certain point, the warning light will illuminate on the dash to let you know to replace the batteries.
Most fob can be pried open to access the battery so you may not have to take your car anywhere. Your owner’s manual may have information on what type of battery should be used and how to replace it. Otherwise, you can find this information online. Make sure that you use the correct type of battery. A different battery will have a different voltage and the system may not register properly, even if the fob still works.
If you have multiple key fob, it's a good idea to replace all of the batteries at the same time as they tend to run out at the same time. Keep in mind, some vehicles may require a reset procedure before the low battery key fob light will turn off.
Is it safe to drive with the key fob battery low warning light on?
This light doesn’t affect drive ability so it is okay to use the car normally if the light is illuminated. If you let the battery get too low on voltage, you may not be able to start the car. Don’t ignore the light and change the batteries out to prevent this from happening to you.
How to Reset the FOB Remote Starter Key?
If you have recently changed the battery of your fob remote car starter or if it has ceased to work it may have fallen out of sync and needs to be reset or reprogrammed. Depending on the type of car you own and the type of fob remote car start you have, this process may vary. If the general reprogramming instructions don't work for you, try the suggested troubleshooting options to resume enjoying the convenience of this technology.
Gather all of the fob remote car starters for your car, unless you only have one. Get into the driver seat of your car and ensure that all doors are properly closed.
Insert your key into the ignition turn it to the "On" position — right before actually starting the car, the lights should turn on. Press and hold the "Lock" button on your fob remote car starter for one second. Turn your key to the "Off" position — the car lights should turn off. Do this within five seconds of turning the key to the "On" position and don't remove the key once you've turned it to the "Off" position.
Repeat step two-three more times, for a total of four cycles. On the fourth cycle, the locks should make a noise when you turn the key to the "On" position, signalling the remote fob has entered programming mode. Press and hold the "Lock" button on the key in the ignition and on any additional fob remote car starters you may have. Turn the key to the "Off" position. Do this within ten seconds of turning the key to the "On" position for the fourth time.
Remove the key from the ignition. Step out of the car, shut the door and test your fob remote car starter to check if it has been reset. Repeat the process, if necessary, but if it continues to fail to try the troubleshooting options.
Check your fob remote car starter's battery. Replace it if your not sure if it's working and test the remote. If the battery is not the issue, proceed with the next steps.
Consult your fob remote car starter's instruction manual. If you have lost it, go to Program Your Remote's website. Here, you'll find a repository of hundreds of fob remote car starter instruction manuals free for you to consult. Browse the website for an exact match to your remote, the model you own may have very specific resetting instructions.
Check your car's owner's manual. If you have misplaced it, go to the Owner's Manual Source website. Here you can find hundreds of owner's manuals. There is a chance you'll be able to find resetting instructions for your car remote there.
Call your dealership and ask them for instructions on how to reset your fob remote car starter over the phone. They may ask you to bring the car in for a service call, in which they will reset the car remote for you. Some car remotes are manufactured in such a way that only the dealers can reset them. Prepare for a service charge.
Today’s key fob/smart keys provide convenience -- and cause problems
Once in the vehicle, the driver steps on the brake pedal (or clutch in an M/T car) and presses the start button to fire the engine.
If the remote’s battery is dead, the engine may still be started by pushing the start button several times (or pressing the button steadily) until a green light in the button flashes. Then touch the remote to the start button. You’ll hear a tone alert. Press the start button within 10 seconds to start the engine.
If the remote is left inside the vehicle, the doors will not lock after the driver has exited the vehicle. This prevents the remote from being locked inside the vehicle. The engine may be shut off by quickly pressing the start/stop button two times quickly or by holding the button in for 1.5 seconds.
Slight parasitic draws can pose a problem. While the vehicle’s system will (or should) go to sleep after a specified time (after the vehicle has been shut off, parked and exited), the proximity of the smart key to the vehicle can result in the possibility of a dead battery if the smart key remains in close proximity to the vehicle.
For instance, if the vehicle is parked close to a house, where the driver’s smart key or proximity card is stored within the design range of the system (for instance, with the smart key in a purse or wallet that’s within the key’s transponder range). If the system is constantly kept “awake,” this parasitic draw can depending on the circumstances, result in a dead vehicle battery.
If a customer has a recurring issue of a drained battery, make it a point to ask about where the smart key is stored overnight in relation to the parked vehicle. Parasitic draws also can affect the battery in the remote key fob. If routinely stored within the reception range of the vehicle, the fob battery may prematurely die.
Another potential concern relates to plastic proximity cards. If the card is stored next to a cell phone (in the driver’s pocket, for example), it may be possible for the cell phone to erase or “scramble” the program in the card.
While not a common occurrence, this is simply another potential concern to be aware of. Again, vehicle system designs vary. Some owners’ manuals advise against storing a smart key in close proximity to various electrical devices where certain frequencies/fields may affect the key, such as TV sets, battery chargers, lamps, etc.
Chrysler’s newer vehicles have gone wireless. One of the new systems is the Wireless Ignition Node (WIN). This system uses a transponder remote key less entry fob integrated key (FOBIK) which replaces the traditional metal key. With all of the functions of a traditional remote key less entry fob, this unit also has a metal key blade for valet functions to lock the glove box and to open the door in the event of a dead battery, a remote key less entry failure or a Bus failure. This unit serves as the remote key less entry fob and the electronic ignition key.
The functions of the WIN are:
– Sentry key immobilizer (SKIM)
– Wireless receiver for remote key less entry
– Brake transmission interlock (BTSI)
– Clock master
– Steering column lock interface (BUX) for export only
– Tire pressure monitor (TPM) system
– Remote starting
– Electronic ignition switch
When entering the vehicle, the FOBIK is used to open the door locks and disarm the alarm system via the remote key-less entry. The FOBIK is then inserted into the WIN, much like an ignition key. But the similarity ends there. When the FOBIK is near the WIN, it transmits a secret key code via radio frequency to the WIN which in turn passes this information on to the controller area network (CAN). The WIN is hard wired to the CAN C Bus. The signal is then sent to the power train control module (PCM). At this point, if it is a valid key, the immobilizer is satisfied and the vehicle is ready to start. The signal is then passed through the central gateway on the vehicle, usually the Totally Integrated Power Module (TIPM).
This information is then gathered by the other controllers via the CAN B, the CAN Interior High Speed (IHS) or in some cases the Locale Interface Network (LIN) Bus. Once the FOBIK is turned to the “start” position in the WIN, the WIN again transmits a message on the CAN Bus for starter engagement and when it returns to the run position, the “ignition on” functions through the PCM and the central gateway to the other modules. The WIN then monitors the tire pressures over the bus and provides the BTSI function via a hard-wired input from the shifter assembly and brake switch.
The system became available on some 2007 vehicles and was standard on all Chrysler, Dodge and Jeep vehicles by 2009.
