If your keys won't unlock, you might find a mechanical slot in the trim around your door handles or elsewhere on your car (consult the owner's manual). Insert the mechanical key and try again. If this doesn't work there are some cars that have an app that can open doors remotely. For instance, the FordPass Connect app, the myChevrolet mobile app and myMazda app permit owners to open the doors using smartphones. However, these apps are subject to a monthly cost.

Reprogramming
The secret world of car key fobs is more intricate than what some myths would suggest. Basic fobs function using radio frequency signals that are specific to each vehicle. The fobs must be programmed correctly in order to be able to unlock and start the vehicle. Reprogramming a key fob is not as simple as pressing a few keys. It's usually handled by the dealer.

Certain manufacturers, like Mercedes utilize proprietary technology that only the dealership is capable of creating a new key fob and then resync it to your vehicle. However, some independent shops can provide this service as well, so be sure to check reviews and prices before selecting the right shop.
Certain car models erase all other fobs once they are reprogrammed. This means you'll need to have any additional fobs programmed by an expert. This is a costly proposition especially if you're only just one functional fob. Even in the event that the mechanical key will not work to start your vehicle, it's a great idea to have a backup that can open the trunk and doors.
Be prepared for a gruelling experience if you choose to reprogram your fob by yourself. You'll be disappointed by numerous guides on the internet that claim to be successful. Many of these guides were written by people who have no prior experience in this field, and they're often founded on unsubstantiated claims. Some of these guides claim that you can easily program your car key fob with just the click of a button. This is a false claim.
Most key fobs are secured by a clip made of plastic that is easy to remove but the battery is inside the circuit board, so you'll have to carefully pry it out using a device. Once you've gotten inside, you'll be able to find the button cell battery, which is usually a small watch battery that is available at most pharmacies or home improvement stores. It's typically easy to replace the battery. Before replacing the whole device, you should try it first.
Replacement
If a car key fob is damaged or fails to function it is crucial to know that there are a few ways to remedy the problem. An easy fix could be as simple as replacing the battery or programming the key fob but a more thorough repair might be required. It's also beneficial to keep a spare fob in case one gets lost or stolen.
Modern key fobs are more expensive and harder to replace due to the fact that they have the physical key and electronics. Some "smart fobs" include remote starters. It's therefore important to understand that it can take up to an hour to have an alternative key fob cut and programmed for your vehicle.
Fobs communicate with the car's receiver using a small radio transmitter on circuit boards. By pressing a button, the transmitter emits an RF signal specific to the car's receiver. The receiver recognizes and compares the signal to preprogrammed codes. This lets the driver unlock the vehicle and begin it from a distance, without inserting the key into the ignition or turning a lock.
If the buttons on your key fob do not respond or function intermittently it could mean that they've been damaged by water or other causes. It is possible to repair the fob by taking it apart and check for damaged or non-responsive buttons. If this doesn't solve the issue, you can try reprogramming the fob or getting a new one.
You should check with an auto dealer in your area or a locksmith prior to purchasing a replacement keyfob online to make sure it's compatible with the security system of your vehicle. There are many aftermarket fobs less expensive, but it's crucial to research the brands and read reviews prior to trying to program them. Certain fobs can be programmed by an experienced locksmith however, other models require programming equipment that only a mechanic or dealer is able to use.
