Keyless Entry System

Keyless entry systems operate by sending radio signals, and then looking for the response signal from the key fob.

Some systems have an additional receiver in the trunk of the car that will open automatically when you waggle your foot under it.

Each key fob is given an individual digital identification number by the manufacturer. The fob is programmed with a unique process called "programming". This usually involves turning on the ignition of the car repeatedly in a specific sequence. It could also require pulling or pushing various buttons and levers or the removal of fuses.

Once a key fob has been programmed into the keyless system of your car, it transmits a digital identification code and a function code that instruct the car on what to do (lock, unlock or open the trunk). The car's receiver verifies that the transmitter is the person it claims to be through an authentication and encryption procedure. The onboard computer will unlock the vehicle and start the engine if it's authenticated.

There are fears that a skilled criminal could intercept the code transmitted between the key fob and the car. This would require a special device to record the transmission then retransmit it when the system isn't expecting it. Most keyless entry systems use the rolling code method to combat this.

Most key fobs have one hole that can be used with an screwdriver or similar tool to open the case, but it's best to wedge your pry tool around the outside of the case first, just as you were peeling an apple or orange. Do not apply too much pressure, as the case of the fob is usually made of plastic and may break or crack if you apply too much pressure to it.

After the new battery has been put in place, try using your key fob once more to see if the battery has fixed the issue. If this doesn't work then you'll have to determine if the fob is experiencing something more complicated that requires professional diagnosis. If this is the case, you could need to have it reset by a dealer or you may need to purchase a replacement key fob entirely.

To fix this, remove the batteries with care and clean each button using a cotton swab that has been submerged in rubbing alcohol. Make sure to dry them thoroughly before installing the batteries.

It's possible that your key fob has been damaged in some way, such as being dropped on concrete or accidentally scratched. If this is the case using a different key fob to verify its function might reveal that it has simply been damaged and needs to be replaced.
