Power locks question?

[MitchFong]

So seeings how you can unlock the drivers side door and the passenger side unlocks aswell. Is there an alarm system out there that will give the e30 remote keyless entry? Im after breaking a few keys in cold weather and i figure its time to check out keyless entry. Doesnt seem like it would be that hard if you could find an alarm system that would include keyless entry as an option. Anyone do this with their car? I would like an alarm that beeps when i engage the alarm and also locks/unlocks the doors. So press the button, doors lock and a little beep to let theifs around know the car is protected.
Any suggestions on a good system for this?

search, i know there is some simple ebay module you can splice into the central locking in the trunk for keyless, and if I recall correctly you can get one with an alarm option.
