2021 Nissan Altima: doors won't lock, open or latch

Filed Jul 7, 2026 · Electrical · TX

Door lock actuators have failed completely on 2 doors, and intermittently on 1 door of a 2021 Nissan Altima. They do not respond to either the key fob or door button. There are no warnings or indicators associated with this component so it is unknown when the failures first occurred, but it was first noticed in summer of 2025. The components have not been inspected but could be made available for inspection if requested. Not being able to unlock doors could present an entrapment hazard in the event of a collision. The doors remaining unlocked is a safety concern as there is nothing preventing the door from potentially being opened while driving, and a security concern as the vehicle may inadvertently be left unlocked even if the lock buttons are pressed on the key fob and/or door. Numerous official and anecdotal consumer reports exist but at the time of this submittal the manufacturer has not issued any notices or recalls regarding this problem.

Rear door locks both do not work other than manually locking. Reported incidents online show many others have had newer Nissan vehicles like our 2021 Nissan Altima with the same issue, some have been locked in the car and had to climb out the window and others said the door unlocked and opened while driving. This is a big concern for me as a mom who has a son driving this car, the entire reason was that the safety ratings were good on this AWD full size 2021 vehicle. We bought it certified pre-owned from the Nissan dealership 2 years ago (2024) and after 1 year, both locks stopped working unless locked manually. The actuators should now have stopped working with a car only 4 years old at the time. Now is it 5 years old, still very new, and the safety issues I've read others have had is very concerning. There was a previous recall on earlier Nissan models, and I wish Nissan would recall these newer models too since you see class action lawsuits and much concern online about the many people having this issue.

Purchased the car in June of 2024 with around 33,000 miles. I thought the doors were locked and someone was able to just open my back door when my car was unattended in a store parking lot; the car was supposed to be locked. Lights and horn started going off. Being a female with a child this is a very scary issue. The idea that anyone can get in when you think the doors are locked or vice versa, in the event of an emergency no one can get in because the doors dont unlock. It started with the passenger side rear door lock not working with fob or button. The lock needs to be done manually. The dealership looked at it and said they could not replicate the problem and everything was working. Now both rear door locks dont work with the buttons or the key fob. The rear doors have to be locked and unlocked manually all the time. Car is currently at the dealership and they confirmed the issue and are telling me that the BCM (i believe is what they said) needs to be replaced and reprogrammed. The car only has approx. 42,500 miles. The other issue with the car is the automatic emergency braking system light comes on and flashes on the dash. It is very random and sometimes it doesnt do it at all. There can be nothing in front of me on the road when it starts flashing. It also does it in all weather conditions, and even when its dry. There have been multiple issues with this car since the day I purchased it.

Based on comments from various post online, it is a common issue that the doors’ lock on altimas with no warning or reasoning just stop working. Whatever position the lock is in, is the one that the lock will stay on even if a safety feature that’s advertised and you expect is for the Altima to automatically lock up when you begin to drive. At this point my personal Altima has not been inspected or fixed by anyone, just a day to day experience of having to check my backseat before getting in to make sure no one is in the back of my car because the doors do not lock. It’s been since about February that the car doors locking mechanism will not engage on two of my car doors, even if you press the lock/unlock switch inside of the door, the lock/unlock button on the key fob, nor the button on the outside of the door handle.
