How to Deal with Repeated Automatic Door Locking and Unlocking?
2 Answers
Press the disarm button twice to completely deactivate the security system. If it doesn't deactivate, within 30 seconds after pressing the disarm button, turn the car key to ACC ON and then back. After turning off the engine and removing the key, if the doors are not locked with the remote, they will not automatically lock even after a long time. If the unlock button on the remote is accidentally pressed while locking, the doors will automatically relock after a short period if no one is present. This feature will be disabled if someone opens the door.
The other day while driving home, my car doors suddenly started locking and unlocking on their own, repeatedly making noise like crazy, which scared me out of my wits. I thought someone was playing a prank, but after checking the remote key, I found the battery was nearly dead, causing unstable signals. I simply replaced it with a new battery, and the problem disappeared—so convenient. Actually, such repeated door antics could be due to key interference or weak signals; sometimes keeping a phone too close can also cause interference. Remember, don’t store the remote near electromagnetic devices, and make it a habit to check the key’s battery level—test the remote’s response monthly. If the issue persists after replacing the battery, it’s likely a fault in the door control module, so head to the repair shop ASAP. Safety first—don’t delay, especially before night driving.
