I have what I've been told is a rather unusual security key system on my 94 Corolla.
It's an electronic type key (but there is no battery in it). It has with three small brass contacts on the end. It fits into a small letter box shaped hole that has three brass contacts to marry up with the contacts on the key.
The key does not turn, but is jiggled up and down until the red security light on the dashboard goes out; then the car can be started.
This system has proved troublesome, the key slot and the contacts seem very cheap and flimsy and after a while have to be prised out to again for them to make proper contact with the key.
The key slot is connected to three different coloured wires. Red, White and blue. Because this system is troublesome I would like to get rid of the whole thing, but understand this might be difficult because like all security systems are designed to be not easily by-passed.
It was not factory installed, but was installed on the car at a later date by a Toyota dealer. ( I know this because it has a Toyota sticker on the window, but have no idea what dealer or where). When I mentioned it to a local Toyota dealer they didn't seem to have any familarity with it at all.
What would be my best way forward to deal with it, do you think? I know this is a maintenance newsgroup, but I am so totally out of my depth here. Might anyone know of some specialist of some kind around north west London that might be able to deal with it. Grateful for any advice.
