Most modern cars are fitted with electronic locks. Electronic locks offer a number of advantages to traditional auto locks. Firstly, they are much more secure. Because there is no physical keyhole into which a key is placed, it is hard for a thief to 'pick' an electronic lock. Secondly, electronic locks are really convenient as they allow you to open the car doors and start the engine at the press of a button. However, occasionally, your electronic car lock may stop working. Below is a guide to the steps you should take if this occurs.

Check the battery and electrical connections

Your electronic car lock relies on power supplied by the battery in your car. If the battery is dead or if the cables connecting the battery to the car's electrical system are loose, you may not be able to unlock an electric car lock. The first step you should take should be to check the auto battery and the electrical connections. If the battery is damaged, you may see liquid dripping from it. Do not touch this liquid -- it is battery acid and can cause serious burns. If the battery appears to be in good condition, you should check that the positive and negative cables which are attached to the terminals are secure and free of any corrosion. If a connection is loose, you should reattach it.

Check and change the battery in your key

Many auto keys are fitted with a small battery that is similar in size to the battery found inside a wristwatch. This battery provides power to the transmitter, which sends out the signal to unlock your car. If this battery is dead, the unit will be unable to send the unlock command to your car's security system. Ideally, you should work out the type of battery your electronic key requires so you can invest in a spare. The spare battery should be kept in your glove compartment so you can install it in the key when the original battery fails.

Call an auto locksmith

A car locksmith is a contractor who specialises in auto locks. They will have spare batteries for most types of keys. If replacing the battery does not allow you to gain access, the locksmith can use specialist computer software to gain entry to your car so that you can drive it to the nearest garage for further repairs. If you would like further information, you should contact an auto locksmith today.
