JR: I went to Super Auto Bacs today and checked their alarm systems w/keyless and they said their systems aren't compatible with vacuum door locks. So, what systems are compatible w/ door locks? TIA JR_Rider - 2/4/2005 9:46 PM
There are systems that offer any single or combination of feature which you so desire. I would recommend getting an alarm with keyless entry together, because it is just easier that way. I decent Viper system will probably be around 250 installed. Best Buy carries Viper, but you should always shop around. Good luck, and if you have any other questions, feel free to ask us. 
Whose systems aren't compatible with vacuum locks?? If they told you Viper systems aren't compatible with vacuum shops, you should never go back to that shop!! No, I am serious, they have absolutely no idea what they are talking about and I would not want them going anything to my car. And remember when having an alarm installed, creativity is your friend. There is no purpose to having an alarm if everbody knows where the brain is mounted! And in case you didn't know, alarm shops will install the brain under the driver side dash or driver's seat. Spend the extra money to have the brain relocated, it might not even be an extra charge. There are plently of great locations on the passengers side!! Oh yeah, many shops include installation in the price the quote you.MRTIKKET - 2/7/2005 7:06 PM
My 300SE, obviously has vacuum door lock too. I have keyless entry, no problem. The company that makes Viper's electronics also sells a generic brand to installation shops, which my shops carry. Cost is about $135.00.
Labor on an MB. could take a couple of hours. Not a big deal. Go to a good stereo installer and tell them you want a "Concepts" keyless entry.
If you can't find one, let me know and I'll send you one.
