Car Key Repair - How to Fix a Dead Remote
Car remotes provide a wonderful convenience for drivers. They can unlock doors, access trunks, and even start the engine. However, they can stop working at inconvenient times.
Before you head to the dealer, consider some quick fixes in case your key fob isn't working. These tips could save you money.
Keyless Entry System
There's no need to search for keys in your pockets or purse. Just walk up to your car, press the button on the keyfob, and the doors will open and the engine will start. It's a practical feature that has made the world of car driving more enjoyable and more secure. However, just like any other device that has a keyless entry system, the keyless entry system may fail due to repeated use or due to other reasons. If you've encountered issues with yours, you have two options: Go to the dealership or contact a local locksmith.
The way that a keyless entry system operates is by sending out radio signals and then searching for a corresponding response signal from the key fob. If the system is able to recognize the signal, it triggers to unlock the vehicle doors and activate the computer onboard. Certain systems have another transmitter located in the trunk of the car which opens it when you waggle one foot underneath it.
Each key fob is given an individual digital identification number by the manufacturer. A specific process of technology called "programming" is used to configure the fob with a specific car's system. This usually involves turning on the ignition of the car repeatedly in a specific sequence. It could also involve pushing or pulling different buttons and levers, or the removal of fuses.
Once a key fob has been programmed into your car's keyless system, it transmits a digital identification code and a function code to instruct the car on what to do (lock or unlock the trunk). The car's receiver verifies the transmitter's identity through an authentication and encryption process. The onboard computer will allow the vehicle to be opened and start the engine if it's authenticated.
A clever criminal could intercept and use the code sent between the keyfob and the vehicle. This would require a special device to record the transmission then transmit it again when the system isn't expecting it. Most keyless entry systems utilize a rolling code method to prevent this. This ensures that every new transmitter signal received by a car has a counter that differs from the previous one.

If you must move them, do so with care as some key fobs come with fasteners that are able to pop open and scatter key fob pieces all over your living room.
Most key fobs have a single hole for the screwdriver or another pry tool to open the case, however it's a good idea to put your tool on the outside of the case first, as if you would peeling an apple or orange. Do not apply too much pressure, as the case of the key fob is usually made of plastic, and it is prone to break or crack when you apply too excessive force.
When you're ready for replacing the battery, make sure to match its size and type to your key fob. Some key fobs come with two batteries while others only need one. The wrong battery could cause your remote to become useless.

If this doesn't work you'll need to determine whether your fob is experiencing a more complex issue that requires a professional diagnosis.

Make sure to dry them thoroughly before installing the batteries.
It's possible that the key fob has been damaged by accident, such as being dropped on concrete or unintentionally damaged by something sharp. If this is the case using an alternative key fob to test its functionality could reveal that the one you have been damaged and requires to be replaced.
