Car Key Fob Repair - How to Get Back on the Road Even If Your Keyless Entry isn't Working
Over time, key fobs could have issues, such as a malfunction. Certain issues might require professional attention, but many can be resolved at home.
The first step is generally to replace the battery. Most fobs utilize flat watches that are easy to find at auto parts stores.
Dead Battery
If the battery for a key fob fails, it can be a major inconvenience particularly if you're away from home. There are ways to get your car back on the road in case your keyless entry system isn't working.
One of the first things you should examine is to determine if the buttons on your key fob function. If they do not then the issue could be with the car's locks.
If the keys aren't unlocking you need to look for a mechanical key slot hidden in the door handle trim or in another location on the vehicle (consult the owner's manual). Insert the mechanical key and try again. If this doesn't unlock the door, some cars come with an application that lets you unlock the door remotely. For instance, the FordPass Connect app, myChevrolet mobile app and myMazda app permit owners to open the doors using smartphones. However, key repair car require an annual cost.
You should also check whether your key fob won't drain the batteries of your car by resting on them. A dead key fob will quickly drain your battery, especially when you use its remote feature while watching TV or talking on the phone.
A key fob that's low on battery can be started by holding 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 doesn't work try testing it in a car with an ignition button. If it fails, the fob battery probably requires replacement. It's a good idea to keep an extra key fob in your backpack or purse.
Damaged Buttons
If your key fob isn't able to open doors or start the vehicle remotely, it's possible that one or more of its buttons have been damaged. Your key fob likely contains an electronic circuit board that has "contact pads" for each button. These little pads are coated with an electrically conducting film that wears down over time. This wear can cause your fob to respond less quickly, or not to respond at all.
The good news is that the pad inside the car key fob is easy to replace, and is done with the help of a simple flathead screwdriver. If the case is damaged or badly smashed, it will be difficult to open. You'll have to take it to an auto repair shop to get the fob repaired.
It's not common for a key fob be dropped, trampled on, or exposed water. These incidents can cause physical damage, such as bending and snapping the keys.
This could also cause internal damage to the fob that could result in an issue. This is why it's always recommended to keep a spare key fob inside your wallet or pocket in case you damage the one you own.
If your key fob's buttons aren't working as they should, you should first verify that the battery is in good condition. Key fobs don't need any special electronic device. They utilize the same battery for two dollars that is used in hearing aids and watches. These batteries are available at drug, hardware, and online stores.
If the battery is functioning properly it is possible that the buttons are worn or dirty. You can easily clean them with a damp cloth. If they're still not responding, try a different key fob to determine if the issue is with yours or with a particular type of car key fob. If the other key fob works, then yours may need to be reprogrammed or replaced.
Reprogramming
The hidden world of car keys fobs is much more complex than many myths suggest. Basic fobs function on radio frequency signals unique to each car. The fobs have to be programmed correctly in order to open and start the vehicle. Reprogramming a key fob is not as easy as pressing several keys. It's usually done by the dealer.
The process of reprogramming a fob is based on the model and model year of the car you own and it's essential to consult the owner's manual to get step-by-step instructions. Certain manufacturers, like Mercedes have proprietary technology that only the dealership is capable of creating a brand new key fob and then resync it to your vehicle. However, some independent shops can provide this service too, so be sure to look up reviews and prices prior to selecting a shop.
Some car models will erase all other fobs once they're changed. This means you'll need to have any extra fobs programmed by a professional. This can be costly especially if you're only down to just one working fob. It is always advisable to have a spare mechanical key that you can use to unlock the trunk and doors even if it doesn't start the car.
If you decide to try and reprogram your fob on your own be prepared for a difficult journey. You'll be disappointed by the numerous guides on the internet that claim to be successful. A majority of these guides were written by people who have no experience and are based on unsubstantiated assertions. Some of these guides claim that you can program your car's key fob yourself with only a few clicks. This is a false claim.
The battery is typically held in place with a plastic clip, which can be removed easily. However the circuit board houses the battery, so you will need to carefully remove the battery using the aid of a tool. Once you've got 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 at home improvement stores. The replacement of the battery is generally a straightforward procedure, and it's always worth trying first before replacing the entire unit.
Replacement
There are many ways to fix a damaged or non-functioning car key fob. It's as easy as replacing the battery or reprogramming the key fob, but a more thorough repair may be required. A spare fob is useful in the event one is stolen or lost.
Most modern key fobs include a small physical key, in addition to the electronic components, making them both pricier and more complex to replace than traditional keys. Certain "smart" fobs even come with a remote starter. As such, it's important to know that it could take up to an hour to have a new key fob cut and programmed to your vehicle.
Fobs make use of a tiny radio transmitter that is mounted on a circuit board to communicate with the car's receiver. By pressing a button, the transmitter sends an RF signal that is unique to the car's receiver. The receiver recognizes and compares the signal with preprogrammed codes. This allows the driver to start the car from a distance without having to put the key in the ignition.
If your key fob buttons are not responding or working in a sporadic manner, they may be damaged by water. You can repair the fob if you take it apart and check for broken or non-responsive buttons. If this doesn't resolve the issue, you can try reprogramming your fob or buying a new one.
It is recommended to consult a local auto dealer or a locksmith prior buying a replacement keyfob on the internet to ensure that it's compatible with the security system of your vehicle. The fobs from the aftermarket can be less expensive but you should look into the brands and read reviews prior to attempting to program them yourself. Some fobs can be changed by a locksmith who is reputable however, other models require programming equipment that only a technician in the automotive industry or dealer is able to use.
