Sunday night i go to walmart around 8. i come back out and try to stick my key in my door. but for some reason its not going in. i shake it around a little and get it in but then it wont turn after a little forcing i get it unlocked and drive home. next morning come out and take a look at it. and their was half of a hair pin stuck in my key hole. so now my key lock doesnt work half the time. and now i really want to buy a security system. and this goes out to the asshole that tried to steal my rx7. my rx7 beat you bitch anyways, any suggestions on type of car alarm?
