Recommendation for Keyless entrance/FMH/alarm?

[fikse]

My doorlocks are quite worn, so I'm in thinkering getting some remote close/unlock system. After a bit searching on ebay, I see there is alot of brands, most chinese stuff but also some that looks like quality.
I'm not into the most advanced one, but my priority is that the electronics will not fail even when it's freezing or very moist.
In UK Tatcham is something to look out for, but does US have some similar system for quality control of alarms/immobilisers?

So, what I look for is
#1 an keyless entry (that must interact with MS's central lock)
#2 follow-me-home-lights (it's dark here, during winter season)
#3 alarm with coupe sensors.

Other stuff like automatic closing of windows would be nice, but not something I would prioritize :-)

Answer myself: 3 options seems better than the rest: Viper LED 2-way remote start, Cobra , and Meta HPA 1.5
All of these have encrypted communication, and all seems to have OK quality.
None of them has even a thought of FolloMeHome-lights, so this seems to come in a separate "thingy".
