I got a La Gard Smart Gard off a AMSEC safe and I have the internal lock and external keypad on the table here. We do not have any of the codes for this lock. I am trying to do a hard reset to put it back to the factory program code so I can program it with my own codes. This the old style of Smart Gard manufactured in 1999 (the lock). The lock is old by was pretty expensive, so I'm trying to reuse it. I pulled the spec sheet on the IC and it seems different from the La Gard 4200 where you short pins 1 and 6 and do a procedure with the key pad. Is anyone willing to share how this procedure is done on a Smart Gard? There is very little information out there on this specific lock. If the lock is not resettable, is it possible to purchase a new electronic lock and use this keypad? What type of lock would I have to get?
