My 2016 Toyota HiLux has a door sensor issue. I had the engine cleaned and now can't lock the car with the key fob. When driving the car beeps showing door open. I have to lock it manually, how can I fix this issue?
Check that the key fob is working, try the spare. Was something dislodged when the engine was cleaned, or is it just a coincidence that the problem cropped up at the same time? Have your dealer look at it for you. Or you could disconnect the battery and then reconnect it hoping the computer has reset itself.
