Front door will not lock with key fob

Asked by Jun 11, 2017 at 09:49 PM about the 2013 Lexus RX 350 FWD

Question type: General

Other doors will lock and unlock normally.  No audible beep or lights flashing
when locking.  Will double beep and lights flash with unlocking.  Mirrors retract
normally with locking.  Changed battery with same results.  Is this an actuator
issue?  Does this have to be repaired at the Lexus dealership or can local
Toyota dealership fix it.

Could be a bad actuator or wiring issue. Ask your Toyota dealership if they will work on it. Pretty sure it won't be warranty work at the Toyota place.

If the locks will lock & unlock using the buttons on the driver side door, that probably eliminates a door lock actuator as being the culprit -- if that were the case, you'd have one (or more) locks not working and the car would beep 4 times when you tried to lock it. The fob may have to be "synched" back with your vehicle and I believe only a dealer can help you with that.

Lexus is not the quality that used to be between this issue with the door and a flashing control panel all the deal is want to do is talk you into your new car


Did u ever find out what the problem was xraymd? I seem to be having the same issue.

Unfortunately, yes. Each door has an electric motor assembly that triggers the power door lock. The tiny motor in the assembly burns out eventually. I replaced the first one at a dealer for $1000+, I think. Of course, they only sell you a whole new assembly! About 10 days later, the OTHER front door motor burned out! So, this time, I did more research and was able to find the tiny motor on eBay for <$10. I also found YouTube videos that showed me how to replace the motor into the door assembly (which you have to remove to install the new motor and then re-install the assembly. Everything works great though I’m still fuming at the big money I paid for the first one. I can probably provide more details if you have trouble locating the part or information I’m talking about.

Like the other answers mention, the full assembly is called a door lock actuator. HOWEVER, the real issue is a tiny electric motor INSIDE the actuator assembly. The motor is not sold separately by Lexus. I was able to locate one pretty easily on eBay (as a new part) for <$10 delivered. The rest of the actuator assembly is all mechanical and probably would never have to be replaced. The tiny motor is the only thing I can ever see as wearing out.

Oh, like Bob mentions earlier in this thread, if your Toyota dealer will work on Lexus (as many do especially in smaller towns who have a Toyota dealer but the nearest Lexus dealer is far away), they should be able to handle this job easily since I imagine this actuator assembly or one similar is common on comparable Toyota models (i.e the Toyota Highlander vs the Lexus RX series.
