What to Do When Car Doors Repeatedly Lock and Unlock Automatically?

Visit a 4S shop to check the programming of all four doors. Another possible cause for this issue could be an electrical circuit problem. If no modifications have been made, inspect the module responsible for door operation located near the spare tire in the trunk to see if any connectors are loose.

My car acted up like this last time too, constantly locking and unlocking on its own. It's most likely caused by the remote key fob battery running low, leading to signal interference, or an internal short circuit in the door lock module. You should first try using the spare key to see if that helps. If there's no improvement, check whether the key responds normally when operated close to the car door. If that doesn't work either, you'll need to inspect the vehicle's electrical system, such as checking for blown fuses or sticky door lock mechanisms. This issue is quite annoying and could even drain the car battery. I once encountered a friend whose car had this problem on the highway—we had to pull over immediately, manually lock the doors, and call for roadside assistance. Safety always comes first. Make it a habit to regularly clean the key slot to prevent dust buildup that could cause malfunctions. Don't wait until it becomes serious—find a reliable repair shop and spend a few hundred bucks to get it fixed for peace of mind.

I've seen this situation quite a few times. Doors jumping around on their own can be really unsettling, most likely caused by key signal interference or module malfunction. Don't panic yet—first, park the car safely, try turning off the remote function, and manually open and close the doors a few times. If that doesn’t work, it might be an aging door lock controller needing a reboot or replacement. I remember one time in the garage, my car kept flashing its lights—turned out to be interference from my phone signal. Moving the key away from other electronics fixed it. Safety-wise, never try to handle this while driving to avoid battery overheating or accidental unlocking. Afterward, take the car to a professional shop for a thorough inspection of the wiring—don’t cut corners and risk bigger trouble.

Having driven for many years, I've encountered issues with door locks randomly activating. My advice is to start with simple self-checks: replace the remote battery to see if that resolves it; if not, check if the door handle is stuck and gently adjust it by pushing; if the problem persists, use a multimeter to test the circuit voltage (skip this if you don't have the tools). Regular maintenance can prevent such issues, like cleaning dust from the lock mechanism every six months or using lubricant spray to prevent rust. Avoid disassembling it yourself to prevent further damage—get it repaired promptly.
