Yes, you can pop the steering lock without the key card.

Don't have my thing here at the office, but Its a simple plug in. 12V in and then touch wire to earth. Or something like that.

I won't post it here for obvious security reasons, so you'll have to work it out. It can be done.

Like most things it was borne out of necessity. Some idiot (I'll blame Paul, but was probably me) put on the lock when we had no card for the PGMIV, so had to come up with something.
