I have mine hooked up to a nathan k3 at 200psi which will get the attention of everyone within about half a mile, so I dont really have a need for a keychain alarm, but thats assuming the stock one does its job.

 

where's a good place to get an aftermarket alarm installed in the houston area?

 

That's exactly what I was thinking, they even gave me the big F U when I called in an accident in the middle of the day! It was my daily driver some A hole tboned, they asked if anyone was hurt, I said no, they said they were too busy!!!! Next time I'm going to tell them no one's hurt yet, but the person responsible is going to get punched the F out!
