Key Fob Repair Service

Key fobs can be damaged. Depending on how they're kept and how often they are moved around, their buttons could become stuck or broken.

Fortunately, the majority of key fob issues are relatively simple to fix. However, some issues are more serious and require expert assistance. Locksmiths can be a great resource in these cases.

Dead Fob Battery

Car key fobs are quite intelligent however, that doesn't mean they don't occasionally find themselves in the "not responding" zone. It's time to replace your battery when this happens. This won't fix the issue since there may be a bad connection at one of the terminals on the battery connector.


Car manufacturers are aware of this issue, so they often put a spare mechanical key inside the fob for just the case of an emergency. It is accessible by finding the small release button or latch that is located behind the fob. (Check the user's manual to find out more). By pressing this button, you'll be able to open the fob to reveal a key that you can use to unlock your car.

Another sign that your fob's batteries are dying is that you have to be closer to the car to unlock and open it than you did before. The transmitter of the fob loses energy when its battery is depleted. This reduces its range.

The replacement of the battery is simple and relatively inexpensive. You will need to purchase a button-cell battery (which is similar to a small silver coin) and follow the directions in the user guide to remove the old battery. Replace keys repair in the exact direction as the original one (the positive side facing up towards the buttons). Test the lock/unlock and begin the functions of the fob after reassembling it. Make sure the new battery is installed correctly.

Some key fobs are a little tricky to open but you should be able to open them by placing the latch, switch, or screw on the back of the fob and then tearing it apart. Be careful not to break the fob because you'll need it to work with your vehicle! You can also take the key fob to an expert in case you're not comfortable doing it yourself. Because it's a standard procedure, most auto shops will change the battery inside a fob for a nominal fee. Some dealers may even complete the task for free based on the model and year of your car.

Fob Isn't Working

The first thing you need to do in the event that your key fob doesn't seem to be working is to replace the batteries. This is the quickest fix and will most likely fix the problem. If your fob is still not working after a battery change it may be due to damage or another issue that requires the attention of a professional.

Damage can occur to your car key fob due to a variety of reasons, including physical trauma, exposure to water or a damaged circuit board. These issues could stop your key from transmitting the signal to the receiver inside your car, which will then prevent your car's ignition or doors from unlocking. It is possible that you will need to hire a professional to replace the fob if it's damaged.

Similarly, the buttons on your fob may have worn-out over time due to repeated use. Rubber can wear out and make the buttons less 'clicky' or springy. They can also stop registering your presses. You could try wiping the buttons down and adjusting them, but it is generally recommended to examine the fob by a professional to make more extensive repairs.

You should also double check that the new battery you're using is a precise match to your fob. You can find a list of compatible batteries online or at most hardware stores. You should always consult your owner's manual or engraving on the inside of your fob to determine what kind of battery it requires. A battery that isn't a perfect match can have problems transmitting strong signals or supplying enough power to the internal components of the fob.

In rare cases, the problem could be related to the vehicle's electronic components or receiver. You can test this by using the physical key to open the door, and then trying to start your vehicle using the inductive backup system (if there is). If your key's physical counterpart does not open or start your car, you should have a mechanic check the electronic components and the receiver to ensure they're working correctly.

Fob Is Damaged

A key fob is comprised of many parts, and one malfunction can cause other parts to fail. If a key fob ceases to function, it's important that you look for obvious causes such as cracked casings or a broken component. Check the horn, lights and other parts of the vehicle to ensure that they are functioning properly.

If the key fob is damaged, it's recommended to find a replacement at your dealership or an auto locksmith rather than trying to repair it. The fob may require reprogramming in the vehicle and this can't usually be done at home and requires specialized equipment to do so.

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

The internal wiring of a key fob could also become worn out over time. This can result in buttons that don't function when pressed, or works when pressed very strongly. It can also lead to the car not opening or locking when the fob is pressed.

The majority of fobs have an outer cover made of plastic that can be opened and then cleaned with soap and water. This can often bring a fob back to functioning properly and it's a good idea to do it often to prevent dirt from harming the insides.

A faulty battery is typically the reason why a key fob will not turn on or work. Most mechanics and car dealers can replace the battery quickly. If you're comfortable installing the battery yourself and are able to do it yourself, you can purchase a new one at an online store or a hardware store, and follow the instructions on YouTube or in the owner's guide.

The worst-case scenario is that the key fob is damaged internal damage, such as cracks within 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 dealer to obtain a new key fob and assistance in programming it to your vehicle.

Fob isn't programming.

The car key fob is a convenient method to start your engine and unlock the doors of your vehicle. When they stop working or fail to function, they can be a hassle. In some cases the problem can be solved by replacing the battery. In other situations it may require a more complicated repair. The first step is to figure out the reason why the fob isn't working properly.

The most frequent reason for a fob malfunctioning is that it does not recognize your vehicle. This is because the connection between the remote and your vehicle is cut off. This connection can be restored without the need for expensive key fob repair.

When the key fob is not sending a clear signal, other issues could be experienced. This could happen if the key is damaged or the battery is not functioning properly. In either event, try to reconnect your key to your vehicle. This can be accomplished by following the directions provided on the key fob. Also, you should keep a spare car key in case the primary key fails.

It's possible that the fob isn't getting the signal sufficiently strong from the car. This could be due a weak battery in the car or interference from wireless devices or a problem with the antenna. Using a remote tester, you can test the fob and see if it is the cause of the issue. If the tester doesn't blink when you press one of the buttons, it could be because the battery has to be replaced or that the fob is been damaged.

Another reason that a fob not sending an adequate signal is that the car's immobilizer system may be hindering it. This could be the case if your key fob hasn't been programmed correctly, or if there is a software problem.

If you aren't able to resolve the issue, or it's not worth the effort of trying to repair the fob, then you should look into buying a replacement. There are low-cost options from many online retailers, and some of these can even be delivered to your door.
