Aunger steering wheel lock

[alias]

Hi all,

I've searched and found a few threads regarding cross-locks but was wondering if anyone had played with/seen the Aunger IMMOBILIZER steering wheel lock. I'll get some pics online of the key/keyway (as soon as Photobucket will let me register) but basically it's a 4-way barrel dimple key with a sort of slotted ward so that the key only goes all the way in one orientation.

The one thing in my favour is that the dimples only appear to be of 3 different depths, either shallow, deep or no cut but I'm finding it almost impossible to get to the pins deeper into the lock without knocking or disturbing the rest of the pins in that row. The other difficult thing is applying tension. The only way I can figure to apply any tension is to use something (a bent paperclip at this stage) to get down to the ward into which the slot in the key slides and then rotating it - this too tends to jostle any pins on either side of the ward.

Anyone got any clues, hints or ideas?

I am looking forward to the pics... there are some previous threads on the 4 way cruciform lock... sounds similar to what your decribing, but in a standard pin tumbler arrangment.

Looks like an opportunity to get creative in the tooling department.

This may be a situation where making a round tension tool would help. Get a piece of appropriate diameter steel, aluminum, or copper tubing and notch it leaving 2 or 4 fingers to appy tension. drill and tap the side of the tubing and use appropirate sidesize partially threaded socket head cap screw with head removed to apply tension.
