Q: Keyless Entry Security system problem

asked by on September 29, 2016

I have a 2004 Toyota Highlander that has a keyless entry system. Today I decided to check my oil and tire pressure. When I was done checking the oil, I shut the hood and got into the car to start it but nothing happened at first. Then the alarm starting going off along with a weird clicking noise. I turned the alarm off but the clicking noise continues. I read through the keyless entry security manual and tried just about everything I could but the car still will not start and the clicking noise continues. Please Help!

My car has 131000 miles.
My car has an automatic transmission.

Hi, thanks for writing in. This is likely related to the anti-theft system in the car going into safe mode. This can be caused for a variety of reasons such as dead or weak battery or a short in the theft system. I would recommend taking the car to the Toyota Dealer to have the computer reset as this will usually correct the system’s misdiagnosed theft of the vehicle. While doing this, I would also recommend showing them the batteries (both the car and key fob) to be sure this is not the problem.
