Steering lock ADR

One of my cars has a keyless entry and start system and there is no audible click when it disengages a steering wheel lock? Because I guess there is no steering wheel lock and its a transmission or computer lock instead? So if new cars can have it why not other 'new' cars?

The ADR requires prevention of starting and prevention of moving forward controlled by the one key. The latter can be on steering or gearbox. If its on the gear box it needs to lock in reverse and/or neutral (depending on auto or manual). You are not allowed to be able to remove the key without the lock engaging.

To do this on the gearbox would be very difficult because you need it so the key cannot be removed without putting the car in neutral or reverse.

I think the best way is to come up with a mechanical device linked to the key turning. I can easily adapt a pull solonoid that will pull the pin out when power is applied through the ignition however solonoid malfunction will lead to the wheel locking and that is a risk i cant take. Anything electronic would need some sort of fail safe so you dont find yourself with a locked wheel at 100kph turning a corner on the highway

Zedn,
Have you spoke to any of the clubman kit manufactures. When I was looking at the Kirkham kits in Perth a couple of years ago I asked the owner of RMC, who was giving me the workshop tour, what steering column he was going to use to make it ADR compliant. There was a mention of a colapsable column that was being made in Australia for Clubmans he was going to look at. If these steering columns are used they must use some device to meet the ADR you are looking at. He builds Westfeilds in the same workshop.

Warren,

I havnt heard of the clubby column and i do spend a bit of time on the clubby forum. I will ask some people i know.

Outwest,
I like the brake idea. However to pass the ADR you would need to make it so you cant remove the key without the lock being activated. That is the tricky part. My outlander requires the car to be in park before the key can be removed, maybe it would be the same sort of thing but hooked up to brake light circuit. There is still a problem however that the solonoid could malfunction and clamp the brake line whilst not depressed and lock it off. I suppose if it was only on the rear that wouldnt be too bad a problem.
