Q: Key fob and key don't work

asked by on February 08, 2016

The car's original alarm system has shut everything down. Now the key fob and key won't do anything.

Hello. If there is nothing happening when the key FOB is used and if the car will not start then the battery should be tested first. If you don’t replace a failing battery, it can keep everything except for the alarm system from working. If the battery is fine then the anti theft module is the problem and needs to be replaced.
