Car Key Fob Repair - How to Get Back on the Road Even If Your Keyless Entry isn't Working

Over time, key fobs can experience problems such as losing functionality. While some issues might require professional attention, the majority can be resolved at home.

The first step is generally to replace the battery. Most fobs are powered by flat watches-style batteries that is easily available at hardware stores or auto parts stores.

Dead Battery

If the battery for a key fob fails, it can be a major hassle, especially if you're 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 examine is whether the buttons on the key fob work. If they do not it could be a problem with the car's locks.

If the keys aren't unlocking you need to look for a mechanical key slot located in your door handle trim or in another location on the vehicle (consult your owner's manual). Insert the mechanical key and try again. If this doesn't unlock the door, some cars have an application that lets you unlock it remotely. FordPass Connect, myChevrolet Mobile App and myMazda apps, for example allow owners to open their doors using smartphones. These apps charge a monthly fee for subscription.

It is also important to ensure that your key fob isn't draining your car's battery by resting on it. A dead key fob will quickly drain your battery, particularly if you use its remote feature while watching TV or speaking on the phone.

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

If your key fob doesn't work You can test it in a vehicle that has a push-button starter. If it fails, the fob battery probably needs replacement. It's a great idea to keep a spare key fob in your bag or purse.

Damaged Buttons

If your key fob doesn't have the ability to open doors or start the car remotely, it's likely that one or more of its buttons have been damaged. The key fob may contain an electronic circuit board that has "contact pads" for each button, and these tiny pads are coated with an electrically conducting film that wears down over time. This wear can cause your fob to respond slower or not at all.

The good news is that the pad in the car key fob can be replaced easily, and can be done so by using an easy flathead screwdriver. If, however, the key fob has been badly damaged or smashed in any way, it might be more difficult to open up the case, and you'll be required to take the fob into an auto repair shop for repairs.

It's not unusual for a key fob to being dropped, trampled, or exposed water. All of these incidents can result in physical damage, like bending and snapping the keys.

This can also cause internal damage to the fob that could cause a malfunction. This is why it's an ideal idea to keep a spare key fob in your wallet or pocket in case you break the one you already have.

Make sure the battery is charged first if your key fob buttons aren't working in the way they should. Key fobs do not require a special type of electronic device. They use the same two-dollar battery that is used in hearing aids and watches. These batteries are available at drug, hardware, and  online  stores.

If the battery is in good condition it is possible that the buttons are dirty or worn out. 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 related to yours or with a particular type of car key fob. If the other key fob works it is possible that yours needs to be reset or replaced.

Reprogramming

The world of car key fobs is much more complicated than the myths suggest. Basic fobs operate with radio frequency signals that are unique to each car. The fobs must be properly programmed in order to be able to open and start the vehicle. Unfortunately it's not as easy as pressing a few buttons and with very few exceptions it needs to be handled by the dealer.

The procedure of reprogramming a fob is based on the model and model year of the car you own and it's essential to refer to the owner's manual for step-by-step instructions. Some manufacturers, such as Mercedes have their own proprietary technology that makes sure only dealers can create the new fob and sync it to your vehicle. Some independent shops might offer this service, so make sure to check reviews and prices prior to choosing a shop.

Certain car models erase all other fobs after they've been changed, so you'll need to get any additional fobs professionally programmed as well. This can be costly, especially if your fob has stopped working. It's always recommended to have at minimum 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 attempt to reprogram your fob yourself be prepared for a difficult journey. There are countless guides on the internet that promise success, but you'll likely be disappointed. Many of these guides were written by people with no experience and are based on unsubstantiated assertions. Some of these guides claim that you can program your car key fob with just the click of a button. This is a false claim.

The battery is typically secured with clips made of plastic, which can be easily removed. However the circuit board is home to the battery, and you will need to carefully remove the battery with an instrument. Once you've got inside, you'll be able to find the button cell battery which is typically a small watch battery that can be purchased in most pharmacies or home improvement stores. Removing the battery is typically an easy process, but it's always a good idea to test first before replacing the entire unit.

Replacement

There are a variety of methods to fix a broken or non-functioning car key fob. An easy fix could be as easy as replacing the battery or reprogramming the key fob, but a more thorough repair may be needed. It is also helpful to have a spare key fob in case one is lost or stolen.

Most modern key fobs include a small physical key, in addition to the electronics they use, which makes them both more expensive and more complex to replace than traditional keys. Certain "smart" fobs also have a built-in remote starter. It's therefore important to know that it could take up to an hour to get an alternative key fob cut and programmed to your vehicle.

Fobs make use of a tiny radio transmitter mounted on circuit boards to communicate with the car's receiver. Pressing an appropriate button will activate the transmitter, which transmits an RF signal that is unique to the car's receiver. The receiver receives the signal and validates it against the preprogrammed codes. This allows the driver to start the vehicle from a distance without the need to insert the key in the ignition.

If the buttons on the fob you have purchased fail to respond or function intermittently, it can indicate that they have been damaged by water or other factors. It is possible to repair the fob if you take it apart and examine for broken or non-responsive buttons. If this doesn't fix the issue, try reprogramming the fob, or getting an entirely new one.

You should check with a local auto dealer or a locksmith prior purchasing a replacement keyfob to ensure it's compatible with the security system of your vehicle. There are many aftermarket fobs cheaper, but it's important to study the brands and read reviews before attempting to program them. Certain fobs can be programmed by an experienced locksmith and other models require programming equipment that only a technician in the automotive industry or dealer is able to use.
