Car Key Repair – How to Fix a Dead Remote The car remotes are a great convenience for drivers. They can unlock doors, open trunks, and even start the car. These remotes can stop working at the most inconvenient of times. Before you visit the dealer, try some quick fixes when your key fob stops working. These tips could save you money. Keyless Entry System You don't need to search for keys in your pockets or purse. Simply walk up to your car, press the button on the keyfob, and the doors will open and the engine will get started. It's a simple function that makes driving a car more comfortable and safe. But just like any device, the keyless entry system can fail due to frequent use or due to other reasons. If you have problems with yours, you may either visit the dealer or call an locksmith. The way that a keyless entry system functions is by sending radio signals, and then searching for a corresponding response from the key fob. If the system can recognize the signal, it's triggered to unlock the car doors and also activate the computer onboard. Certain systems have a second transmitter on the trunk of the car that opens it when you waggle your foot beneath it. Each key fob is given an individual digital identification number by the manufacturer. The fob is programmed with a proprietary process called “programming”. This usually involves turning the ignition of the car several times in a certain sequence. It could also require pulling or pushing various buttons and levers or the removal of fuse. Once the key fob has been programmed into your car's keyless system, it transmits a digital identification code as well as a function-code to instruct the car to (lock, unlock or open the trunk). The car's receiver confirms that the transmitter is the person it claims to be by using an authentication and encryption process. The onboard computer will unlock the vehicle and start the engine if it is authenticated. A skilled criminal could snoop and use the code sent between the keyfob's and the vehicle. This would require a device to record the transmission and then retransmit it later when the system isn't expecting it. To help combat this, most keyless entry systems use a method called rolling code that guarantees that each new transmitter signal received by the car has a different counter value than the previous one. Batteries The most frequent reason for car remotes key fobs not working is an inoperative battery. If you have an extra key fob, it's a low-cost and simple fix. The majority of fobs are powered by watch-style batteries that can be bought at hardware stores or big-box stores for less than $10. A quick search of the internet or in your vehicle's owner's manual will provide directions on how to disassemble the fob that you have been using and swap out the battery. Be cautious not to damage any of the circuits or antennas within the case once you've removed your battery. They're likely to hold the key fob's programming to your car's specific model and tampering with them will render it unprogrammable (and probably not work). If you must move the key fobs, take care. Certain key fobs might have fasteners that can easily be removed and scatter key fob pieces across your living space. Most key fobs come with one hole that allows an screwdriver or similar tool to open the case.

Don't apply too much pressure, as the case of the fob is usually made of plastic and may break or crack if apply too much force to it. When you're ready to replace the battery, make sure to match its size and type to the key fob. Some fobs require two batteries, while others only have one. The wrong battery can make your key fob remote useless. After the new battery is installed, test your key fob again to see if it solves the issue. If this doesn't work you'll need to determine whether your fob is experiencing an issue that is more complicated and requires professional diagnosis.

Buttons The little buttons on your key fob are small, and are packed with delicate electronics. It's not a surprise that they'll malfunction from time to time. If the button on your car's ignition suddenly stops working, you can usually fix it yourself. The most frequent reason why the car remote stops functioning is due to dirt or crud have trapped between the button. To remedy this, take out the batteries with care and clean each button using a cotton swab that has been submerged in ruby alcohol. Make sure to dry the batteries completely before reinstalling them. It's possible that your key fob was damaged in some way, like being dropped on concrete or accidentally scratched. If that's the case, using another key fob to test its functionality might reveal that it has simply been damaged and needs to be replaced. The door lock sensor might have stopped working in your vehicle. It's a tiny metal component attached to the key fob's door lock button. It's not uncommon for it to break due to weather conditions or long usage. To activate remote key repairs press your key fob a few times without locking or unlocking your doors to reset it.
