Every once in awhile my fire alarm wont stop beeping. I even wake up in the night with it screaming its $$ off sometimes. What should is do?? Its been happening ever since June or so I think.
It's called a cylinder housing and it contains the cylinder and tumblers. Any locksmith should have one or be able to get one for you.
Stop in at a place that installs remote starters and have them take a look. They may recognize the system, or give you some ideas where to check.
