How long should a car key last? Well that depends on how often it is used, how many times you drop it and how many washing cycles it has been through. But seriously they should last approximately 10 years. After this time the remote may become harder to lock or unlock from a distance. The battery in your key will start draining quicker than expected. This could be from one year and some severe causes the battery could go flat in weeks. Please note battery drainage can also be caused from storing keys to close to the vehicle, the remote buttons beings pressed while in your pocket/bag or storing keys near microwaves or wireless chargers. Also the mechanical part of the transponder key after ten years will be worn and causing damage to your ignition. This will be evident with it working in your ignition but not your doors. Your door lock isn’t used because of the remote and shows the damage your key has done to the ignition. The next question is, how often do you replace your phone or computer? Car keys are basically a micro computer that communicates with your vehicle. Car keys should be replaced once the above symptoms start to show. The last thing you want is your only key to stop working. In some cases it can cost thousands to replace when no keys work.
