This is especially the case if you are away from home. However, there are options to get back on the road even when your car's keyless entry doesn't work.<br /><br />The first thing you should check is if the buttons on the key fob still work. If they do, then the issue may be with the car's locks instead of the fob.<br /><br />If your keys do not unlock, you might find an electronic slot in the trim around your door handles or elsewhere in your car (consult the owner's manual). Insert the mechanical key and try again. If this fails, some cars have an app that allows you to unlock doors remotely.

If it doesn't work the battery of the fob needs replacement. It's a great idea to keep an extra key fob in your backpack or purse.<br /><br />Damaged Buttons<br /><br />If your key fob is unable to open doors or start your car remotely, it's likely that one or more of its buttons have been damaged. Your key fob contains a circuit with "contact pads" that are covered with an electrically conductor film. The film wears off over time. The wear may cause your fob to react more slowly, or even not respond at all.<br /><br />The contact pad on a car keyfob can be easily replaced with the flat-head screwdriver.

All of these events can cause physical damage to the keys, such as bending or snapping them.<br /><br />It could also alter the internals of the fob and could cause malfunction. It is a good idea, therefore, to always carry an extra fob in your wallet or pocket in the event that the one you're using is damaged.<br /><br />If your key fob's buttons aren't working in the way they should, you should first verify that the battery is in good working condition. Key fobs don't require an electronic device. They use the same two-dollar battery that is used in hearing aids and watches. They are sold at hardware, drug, and online stores.<br /><br /><br /><br />If the battery is in good condition, the buttons may be worn or dirty. You can easily clean them with a damp cloth. If the buttons still don't work, try another car key fob. This will help you determine if the problem is yours or a particular model. If the other key fob is working it is possible that yours needs to be reprogrammed or replaced.<br /><br />Reprogramming<br /><br />The hidden world of fobs for car keys is more complex than many myths suggest. The basic fobs work by using unique radio frequency signals that are assigned to specific cars. The fobs must be properly programmed to unlock and begin the vehicle. Reprogramming a key fob is not as simple as pressing a few keys. It's usually done by the dealer.<br /><br />The procedure of reprogramming a fob is dependent on the manufacturer and model year of your vehicle and it's essential to read the owner's manual for step-bystep instructions. Certain manufacturers, like Mercedes have proprietary technology that only the dealership is able to create a new key fob and resync it to your vehicle. Some independent shops may offer this service, so check reviews and prices prior to selecting the right shop.<br /><br />Certain car models erase other fobs after they've been changed, so you'll have to have any additional fobs professionally programmed. This can be costly especially if you're only down to just one working fob. It's always recommended to have at least one spare mechanical key you can use to open the doors and trunk even if it's not able to start the car.<br /><br />Be prepared for a gruelling experience if you choose to reprogram your fob by yourself. There are countless guides on the internet that promise success, but you'll likely be disappointed. Many of these guides were written by people who have no experience and are based on unsubstantiated statements.

The replacement of the battery is generally simple, and it's always worth trying first before replacing the entire unit.<br /><br />Replacement<br /><br />There are several ways to fix a damaged or damaged car key fob.

A spare fob could be useful in the event one is stolen or lost.<br /><br />Most modern key fobs include the physical key in addition the electronic component they use, which makes them both more expensive and more complex to replace than traditional keys. Some "smart fobs" even include remote starters. As such, it's important to understand that it could take up to an hour to get a replacement key fob cut and programmed for your vehicle.<br /><br />Fobs utilize a small radio transmitter mounted on circuit boards to communicate with the car's receiver. By pressing a button, the transmitter emits an RF signal that is unique to the car's receiver. The receiver receives the signal and checks it against the preprogrammed codes. This allows the driver to open the vehicle and start it from a distance without inserting the key into the ignition or turning the lock.<br /><br />If the buttons on your key fob aren't working or responding in a sporadic manner, they may be damaged by water.
