Home security

I believe I need to change the battery to our ADEMCO Vista-20se/Vista-29HWse. I have a key that fits the lock on the box but it won't open it. So the key isn't the correct key or something is wrong with leither lock or key. Can I purchase another key for this box? Or do I call a locksmith or destroy the door? Any suggestions?

Welcome to the forums,

It should be an ademco 1393 key. That key is used by many different ademco type systems.
The lock may be jammed. They aren't very strong. You can use a screwdriver to twist it apart/open and then replace it with a new lock from the home improvement store.

The right key should turn 90 degrees: you might need to push on the door. If the key turns about 25 degrees, you have the right key and it works.

​​Check the edge of thE door for screws: I've seen the door secured with screws and a lock a few times.

Don't forget to let us know the final resolution.
