It sounds like it might be time to replace your car door lock switch.
Here is how you can replace your car door lock switch:
  • Inspect the lock circuit, test out the new switch, fuse, and relay
  • Remove the defective lock switch
  • Install the new switch
  • Test the new switch to ensure it is working properly
If you have a newer car you may need to replace the entire locky system instead of a single lock switch. You can save money with do-it-yourself car fixes and by shopping for
