I couldnt sleep last night so I got pondering about my car and the fact I only have one key for it. I dont fancy paying between £200 and £300 for a new key from a stealship and seems to much bother to track down a local auto locksmith who can recode keys. So I got thinking of alternative ways to keep the security in my car, but also give me a cheaper way of making spare keys, im just spitballing here so feel free to throw your 2cents into the pot.....
Note : both ideas are completely temporary and could be undone easily and quickly if needed.
Idea #1 - Leaving the transponder inside the car
This one might have the masses shouting "you cant do that or it will invalidate your insurance" but keep reading.....
Attach the transponder to the ignition barrel casing within range of the ariel. This will let you get a new blade cut so you can have as many spares as you like, but obviously goes against the idea of an immobiliser altogether because it might aswell just be disabled. Keeping reading! [
I used to have an old austin mini and it didnt have an immobiliser or any other form of security, but many classic car owners put a hidden switch (which only they knew about, and usually under the dashboard for example) that was connected on the wire between the ignition barrel and the stater motor solenoid, so when the driver got in and out of the car they would flick the switch to immobilise/mobilise the car. Probably the most basic form of engine immobilisation
So taking that idea and also the inspiration from Renault's card key from the mk2 Laguna's (because I think card keys are cool!!) I come up with this :
Cut and extend the wires that go from the ignition barrel to the starter motor....
Create a switch, for example I thought it would be cool to cut the memory card slot from an old playstation....
And fabricate it into the ashtray so that it could accept a playstation memory card (internals modified to just simply complete the circuit).
So rather than the switch be part of the car, the memory card acts as the switch to complete the circuit from the ignition barrel to the starter motor. The memory card (aka card key) can be removed everytime the drivers gets out of the car, immobilising the car.
"What happens if you lose the card key?" I hear you cry, well you can just make another one!!!
a theif try to steal my car they will have no idea that they ONLY need a modified playstation memory card to actually start it. If I was going to go with this idea I would obviously disguise the transponder so that should sed theif rip the steering column shroud off they wont spot it.
