Key fobs can experience problems over time, such as the loss of functionality. Certain issues might require professional attention, however many can be resolved at home.
Change the battery is often the first step. The majority of fobs have flat watch-style batteries that are readily available at auto parts stores.
Dead Battery
It can be a real issue when the battery of a key fob dies. This is particularly true when you're away from home. There are ways to get back on the road when your vehicle's keyless entry system isn't working.
One of the first things you should be sure of is to determine if the buttons on the key fob work. If they do, the issue could be with your car's locks instead of the fob.
If the keys aren't unlocking you need to look for a mechanical key slot concealed in the trim of your door handle or in another location on the car (consult your owner's manual). Insert the mechanical key and try again. If this doesn't unlock the door, some cars have an app that allows you to unlock the door remotely. FordPass Connect, myChevrolet Mobile App and myMazda apps, for instance allow owners to open their doors using their smartphones. These apps do charge monthly subscription fees.

Damaged Buttons
It's possible that the key fob has a damaged button. The key fob has a circuit with "contact pads" which are covered by an electrically conductor film. This film wears off over time. This wear can cause your fob to respond more slowly, or even not respond at all.
The pad that contacts a car keyfob can be easily replaced using a flat-head screwdriver. If, however, the key fob is severely damaged or broken in any way, it might be more difficult to open the case, and you'll be required to take the fob to an auto repair shop to be repaired.
It's not common for a key fob being dropped, trampled or even exposed to water. These events can cause physical damage to the keys, which could result in them breaking or snapping them.
This can also alter the internals of the fob and could cause an issue. This is why it's recommended to keep an extra key fob in your pocket or wallet in case you break the one you have.
Examine the battery first to determine to determine if the buttons on your key fob aren't working like they should. Remember that key fobs aren't a special kind of electronic device; they're typically powered by the same two-dollar batteries that are used in watches and hearing aids, which are readily available at drug stores, hardware stores, and online.
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, test a different key fob to see whether the issue is with yours, or a specific kind of car key fob. If the other fob functions then it's likely the key fob you have needs to be reprogrammed or even replaced completely.
Reprogramming
The secret world of fobs for car keys is more complex than many myths suggest. Basic fobs operate using radio frequency signals that are specific to each car. The fobs need to be correctly programmed to unlock and start the vehicle. Unfortunately the process of reprogramming a fob isn't as simple as pressing a few buttons and with a few exceptions, it must be handled by the dealer.
The procedure of reprogramming a fob is based on the model and model year of your vehicle and it's essential to consult the owner's manual for step-by-step instructions. Some manufacturers, such as Mercedes utilize proprietary technology that ensures only the dealership can create a new fob and re-sync it to your vehicle. Some independent shops may also offer this service, so check reviews and prices prior to choosing a shop.
Certain models of cars erase all other fobs once they're programmed again. This means that you'll have to have any additional fobs programmed by an expert. This can be costly particularly if you're just one functional fob. Even if the mechanical key won't start the car, it's a good idea to have a backup key that can open the doors and trunk.
If you attempt to reprogram your fob yourself, be prepared for a gruelling journey. There are countless guides on the internet that promise success however, you're likely to be disappointed. Many of these guides were written by people who have no experience in this area and often are based on unsubstantiated claims. Some of them even state that you can program your car key fob in just a few clicks, which is very misleading.

However the circuit board is home to the battery, and you will need to carefully pry the battery out using an instrument. You should be able to find the button cell battery.

Before replacing the entire unit, it's worth trying first.
Replacement

It's as easy as replacing the battery or reprogramming the key fob, however a more extensive repair may be required. It's also beneficial to keep a spare fob in case one is lost or stolen.
Modern key fobs are more expensive and harder to replace since they have an actual key as well as the electronics. Some "smart fobs" even include remote starters. It's important to understand that it can take an hour or more to cut and program the replacement fob to your vehicle.
Fobs use a small radio transmitter mounted on a circuit board to communicate with the car's receiver. Pressing the button triggers the transmitter, which sends an RF signal that is unique to the car's receiver. The receiver detects the signal and verifies it against preprogrammed codes. This allows the driver to unlock the vehicle and begin it from a distance without putting the key in the ignition or turning the lock.
If your key fob buttons are not responding or working in a sporadic manner, they may have been damaged by water. You may be able to fix the fob by disassembling it and examining it for broken or non-responsive buttons. If this doesn't solve the issue, you can try reprogramming it or purchasing a new fob.
You should check with an auto dealer in your area or a locksmith before purchasing a replacement keyfob online to ensure it is compatible with the security system of your vehicle. Fobs purchased from a third party can be cheaper but you should study the reviews and brands before trying to program them yourself. While some fobs can be replaced by a reputable locksmith others require special programming equipment that can only be used by a car dealer or auto technician.
