I went to custom stereo to have my internet bought alarm installed. They said they may have a representative install the alarm but it would take about 3 days for them to get to it. I would have to admit, it was more complicated than I thought because my vehicle had manuel locks. Somehow, the rep installed the new alarm and also made the doors automatic so that I could open the doors from just the keychain I was given. The rep was great and I got it installed for really cheap. Definitely would go back for anything I would need later!
