Dead Fob Battery

Car key fobs are quite intelligent however, this doesn't mean that they won't occasionally find themselves in the "not responding" zone. It's time to replace your battery if this occurs. However, that's not always the solution to the problem, because you may also have a bad connection on one of the battery connector's terminals.

Automobile manufacturers are aware of this potential issue, so they usually include a spare key mechanical inside the fob in case of this kind of emergency. To access this, find the small release switch or latch located behind the fob (check the user manual for specifics). Pressing this can allow you to unlock the fob, and then gain access to a physical key, which you can use to unlock your vehicle.

You will also need to be close to your vehicle in order to lock and unlock it. This is because the fob's transmitter loses strength when its battery is depleted and limits its operating range.

It is relatively easy to replace the battery. Be sure to purchase the button cell battery (which appears like tiny silver coins) to replace your fob, and follow the user guide or video on how to remove the old battery. Replace the battery in the same way that the previous one (the positive side facing upwards towards the buttons). Test the lock/unlock, and begin the functions of the fob after reassembling it to ensure the new battery is installed correctly.

You can unlock some key fobs by looking for the latch, screw or switch in the back and prying the fob apart. You'll need the fob to work with your vehicle, so take care not to damage it! If you're not comfortable doing this on your own, you can also take your fob to a professional. Since it's a routine service the majority of auto shops will replace the battery on the fob for a small cost. Some dealers might even be willing to complete the task for free based on the model and make of your vehicle.

Fob not working

The first thing you need to do if your key fob isn't working is to replace the batteries. This is the easiest solution and will fix the problem. If your device is not working after a battery change it could be due to damage or another issue that requires the attention of a professional.

The key fob in your car can be damaged due to various reasons, including physical injury or exposure to water or a damaged or corroded board. These issues can prevent your key from communicating with the vehicle's receiver and prevent the doors of your car and/or ignition from unlocking or turning on. If your fob is damaged, it's likely that you'll require a professional to repair the part or the entire device.

The buttons on your fob may have worn out with repeated use. The rubber may wear out and make the buttons less springy or 'clicky' and eventually, they'll begin to fail to register your press accurately. You can try wiping down the buttons and adjusting them to see if that fixes the problem However, it's generally best to take the fob to a professional examined for more comprehensive repairs.

Check that the battery you're using is compatible with your fob. You can find a list online or in a majority of hardware stores. Refer to the owner's guide or the engraving on the fob to find out more. A battery that is not the perfect match may have issues transmitting strong signals or supplying enough power to the fob's internal components.

In rare instances it could be that the problem is not with your key fob, but more with the vehicle's receiver or electronic components. If you have an inductive backup system you can test it by opening the doors with the physical key and beginning the car using the inductive backup (if there is). If the physical key you have isn't able to open or start your vehicle then a mechanic should inspect the electronic components and receiver of your car to see whether they're working properly.

Fobs that are damaged

A key fob is made up of many components that are interconnected and a single malfunction can cause other parts to fail. If a keyfob stops working it's crucial to check for obvious causes like cracked casings or a broken component. Check the horn, lights and other components of the car to make sure they are working properly.

If the fob for your key is damaged, it's recommended to find a replacement at your dealer or an auto locksmith instead of trying to repair it. The fob could require reprogramming to the car this is something that cannot be done at home, and it requires special equipment to do so.

Over time the contacts on buttons of a key fob can wear out. This is particularly true if the device is dropped or left in hot temperatures.

As time passes the internal wiring inside the key fob could wear down. It could result in buttons that don't function when pressed, or only is functional when it is pressed extremely hard. It could also result in the car not opening or locking when the fob is pressed.


The majority of key fobs have a plastic cover which can be removed and cleaned safely with soap and warm water. This can restore a keyfob to its original function. It's recommended to clean it regularly to prevent dirt from damaging the inside.

A damaged battery is usually the reason the key fob will not turn on or function. Many mechanics and dealers can replace the battery in a short time. If you are comfortable installing the battery yourself, you can purchase a new one at the big-box or hardware store and follow the instructions on YouTube or in the owner's manual.

The worst-case scenario is that the key fob has internal damage, such as cracks in the case, tiny electronic components that aren't fully attached to the circuit board, or bent or corroded contact points for batteries. If you notice any of these problems you should contact an auto locksmith or a dealer to obtain a new key fob and assistance in programming it for your vehicle.

Fob Isn't Programming

The car key fob is an easy way to start your engine and unlock the doors of your car. When they stop working or work intermittently, they can be quite frustrating. In some instances the issue may be as simple as replacing the battery but in other cases it could require an even more complex repair. The first step is to identify the reason for why the fob isn't functioning properly.

One of the main reasons for a malfunctioning remote is that it has stopped recognizing your vehicle. This can happen when the connection between your remote and your car is broken. This connection can be restored without the need for expensive key fob repair.

Other problems can arise when the key fob no longer sends a clear signal. This could happen if the key has been damaged or if the battery is dead. In either case, try to reconnect your key to your car. This can be done by following the instructions provided with the key fob. It's also recommended to carry a spare key with you in case you need to make use of it in the event that your primary key isn't working.

It's also possible that the fob doesn't receive an adequate signal from the car. This could be due to an insufficient battery in the car or interference from wireless devices, or an antenna issue. Using a remote tester, you can test the fob to check if it's the cause of the issue. If the tester doesn't light up when any of the buttons are pressing, the battery may need to be replaced or the fob is broken.

A car's immobilizer could also be preventing a fob from sending a clear signal. This could happen if your key fob hasn't been properly programmed or you have a software issue.

If you can't fix the fob or it isn't worth the trouble to try to repair it, you should buy a new one. Many online retailers offer cheap options and some are delivered to your residence.
