I bought a hand gun safe from Gander Mountain about seven years ago.
I can't tell you the name, but it has a four button keypad, and no emergency key lock. If the batteries go dead it has a terminal that you can use a nine volt battery and the default code to get into it, and change the batteries. It came with a base that can be bolted to the floor, or whatever, and you could purchase another plate and install in your car, that way you could take it with you if needed.
It has worked very well, specially if you remember to replace the eight AA batteries every year.
I know it was made in Texas. but I can't for the life of me remember the manufacturer.
It will alarm if you enter three false codes, or even if you move or bump. This was annoying after while, so I cut the one speaker wire off.
The safe gives you a warning that it will alarm, in a mans recorded voice,
" Alarm will sound", and it says this three times before the alarm goes off. The funny part is, and I don't mean to offend you Texans out there. This persons recorded voice sounds exactly like Gomer Pyles voice on the Andy Griffith show. The show where Gomer fights Barney over his right to preform a citizen's arrest. Gomer yells at Barney, " Citizen's arrest" " Citizen's arrest".
Now close your eyes, and say " Alarm will Sound", "Alarm will Sound", but say it with Gomers voice.
I laughed so hard the first time I heard this. I'm hoping that if I ever have a break in when I'm not there that we will be able to catch him cause he will be on the floor laughing so hard.
