vehicle keypad type Engine immobiliser

We have vehicle antitheft device for sale that uses a numeric keypad in which the driver has to enter his personal indentification number (4 code PIN#) before the vehicle will start. The vehicle will not start even if the wires to the keypad are cut. Fits any vehicle.

I was at a freinds house for the night and was warned to put my car in the garage but ignored it and went to bed I thought I herd my alarm go off but it stoped so I thought it was the wind anyway I woke up to find out the next morning some one broke in, cut the alarm wires and tried to take my car lucky for me when he cut the wires the car still didnt start because of the key pad imobiliser but they took my cd so I highly recomend.
p.s I asked for a refund on my alarm. And got it

E30s with the full obc have this built it!!
