Car key fob repair (www.bos7.cc said in a blog post) - How to Get Back on the Road Even If Your Keyless Entry isn't Working

Over time, key fobs may have issues, such as a losing functionality. While some issues might require expert attention, most can be fixed at home.

The first step is typically to change the battery. The majority of fobs are powered by flat watches-style batteries that are easily found at hardware stores or auto parts stores.

Dead Battery

It can be a major problem when the battery of a key fob is dead. This is particularly true if you are away from home. There are ways to get your vehicle back on the road if your keyless entry system has stopped working.

One of the first things you should check is whether the key fob's buttons still work. If they aren't then the issue could be in the car's locks.

If your keys won't unlock, you might find a mechanical slot within the trim around the door handles or in other places on your car (consult the owner's manual). Insert the mechanical key and try again. If this doesn't unlock the door, certain cars come with an app that allows you to unlock the door remotely. For instance, the FordPass Connect app, myChevrolet mobile car key repair app and myMazda app allow owners to open their doors using their smartphones. However, these apps require a monthly cost.

It is also important to ensure whether your key fob won't drain your car's batteries by being plugged into them. A dead fob can drain your battery fast especially if it's used to control the TV or phone while you are watching.

A key fob that's just low on battery can be activated by bringing it up to the start button. This simple fix could save you from having to visit your dealer or Interstate All Battery Centers.

If your key fob won't work You can test it in a vehicle that has a push-button starter. If it doesn't work the battery of the fob requires replacement. This is why it's a good idea to keep an extra key fob in your bag or purse.

Damaged Buttons

It is possible that your key fob has a damaged button. Your key fob likely contains an electronic circuit board that has "contact pads" for each button. These tiny pads are covered with an electrically conducting film which wears down over time. This wear can cause your fob to react more slowly, or even not respond at all.

The good news is that the pad inside the key fob of a car is easy to replace, and is done using a simple flathead screwdriver. If, however, the key fob is badly smashed or harmed in any way, it may be more difficult to open the case, and you'll need to take the fob into an auto repair shop for repairs.

It's not common for a key fob be dropped, trampled on or even exposed to water. All of these can cause physical damage to keys, which could result in them breaking or snapping them.

This could also cause internal damage to the fob that could result in malfunction. It's a good idea so, always keep an additional fob in your wallet or in your pocket in case the one you're using fails.

If the buttons on your key fob aren't working as they should, first check to make sure the battery is in good working condition. Remember that key fobs aren't a special kind of electronic device; the majority of them use the same two-dollar batteries that are used in watches and hearing aids that are readily accessible at drug stores, hardware stores, and on the internet.

If the battery is fine it's possible that the buttons are dirty or worn out and can be easily cleaned using a moist cloth to wipe them clean. If they're still not responding, try a different type of key fob to determine whether the problem is with yours or a specific kind of car key fob. If the other fob is working, it's likely that your key fob has to be reset or even replaced completely.

Reprogramming

The hidden world of car key fobs is more complex than some myths suggest. The basic fobs work on unique radio frequency signals that are assigned to specific cars. The fobs must be properly programmed to allow unlocking and starting the vehicle. Unfortunately, reprogramming a fob isn't as easy as pressing a few buttons and with very few exceptions it needs to be handled by a dealer.

The procedure of reprogramming a fob is based on the model and model year of your car and it's essential to read the owner's manual to get step-by-step instructions. Some manufacturers, such as Mercedes have their own proprietary technology that makes sure only the dealership can create an entirely new fob and then sync it with your vehicle. However some independent shops provide this service too so make sure to look up reviews and prices prior to selecting the right shop.

Certain car models erase all other fobs once they're changed. This means that you'll have to have any additional fobs programmed by an expert. This is an expensive proposition especially if you're only down to one functioning fob. It is always advisable to have at minimum a spare mechanical key that you can use to open the trunk and doors even if it doesn't start the car.

Be prepared for a gruelling experience if you opt to reprogram your fob yourself. There are many guides on the internet that promise success however, you're likely to be disappointed. A lot of these guides were written by people with no prior experience in this field, and they're often based on unsubstantiated claims. Some of these guides claim that you can easily program your car key fob by yourself in just only a few clicks. This is misleading.

The battery is typically secured with an elastic clip that can be removed easily. However the circuit board houses the battery, so you'll need to remove the battery using a tool. Once you've gotten inside, you should be able to find the button cell battery which is usually a small watch battery that is available in most pharmacies or home improvement stores. Replacing the battery is usually an easy process, but it's always worthwhile to try this first before replacing the entire device.

Replacement

If your car key fob is damaged or isn't functioning it is crucial to know there are several options to fix the issue. It could be possible to repair the issue quickly by replacing the battery or reprogramming the key fob. However an extensive repair may be needed. It is also helpful to have a spare key fob in case one is lost or stolen.

The majority of modern key fobs have a small physical key, in addition to the electronics which makes them more expensive and more complex to replace than traditional keys. Some "smart fobs" include remote key fob repair starters. It's important to know that it could take an hour or more to cut and program the replacement fob to your vehicle.

Fobs communicate with the car's receiver using a tiny radio transmitter on circuit boards. Pressing the button triggers the transmitter, and it transmits an RF signal that is unique to the car's receiver. The receiver receives the signal and validates it against preprogrammed codes. This lets the driver unlock the car and begin it from a distance without putting the key in the ignition or turning a lock.

If the buttons on your key fob are not responding or working intermittently, they may have been damaged by water. You can repair the fob if you take it apart and look for broken or non-responsive buttons. If this doesn't fix the problem, you can try reprogramming the fob or purchasing another one.

You should check with a local auto dealer or a locksmith prior purchasing a replacement keyfob online to ensure it's compatible with the security system of your vehicle key repairs. The fobs from the aftermarket can be less expensive but you should research brands and read reviews prior to attempting to program them yourself. Certain fobs can be modified by an experienced locksmith, but other models require programming equipment that only a mechanic or dealer is able to use.
