I have a 16’ Miata and It keeps locking and unlocking while driving. Constantly. Not the auto lock when the ignition is on but back and forth back and forth.

I replaced the key fob battery on both keys, tried driving with each key, still does it.

My car was just in the shop because I hit a wheel on the freeway, hit my radiator and coolant got all over the bottom of the car. Not sure if this has anything to do with it, but it’s been doing it since.

Not sure what else to check. I also turned off the auto lock and it still does it. Could it be a door latch? The keyless entry button? Thanks!
