Central Locking Problem Is200 S

[Stu]

OK, i have a problem with my IS's locking system. I bought the car about 5 weeks ago, and the day after i bought it it went wrong and i couldn't get into it without the alarm going off, as the remote wouldn't work and i had to use the key to open the door. I took it back to the dealer and they sorted it, but it took 3 days to do. They said that the car had somehow managed to wipe it's own memory and forget it had any keys assigned to it. They sorted the problem and said it shouldn't give me anymore hassle. :)

It went wrong again this morning. :tsktsk:

They have now got it back in for repair, and say that it's probably the reciever for the locking system.

Has anyone else had this problem with their car? If so, what was it that actually went wrong? what do i do if it does this when the warranty expires?! :duh:

Funny you should mention it but we have a IS in our workshop at the moment with exactly the same problem.

[Stu]

any ideas as to what is causing it?

Its just faulty Reciever ECU's, there was a simlar problem on the mark 1 Toyota Avensis.

Just got the car delivered back to me, and they replaced the reciever for the central locking system. Hope the new one does better than the other one did!

We shall see how it fares over the next few weeks! :P
