I want to get a whole alarm...remote start...key less entry...all that jazz...but i want to get a number code thing on the door handle...i have a 1997 f150 and i have seen trucks with the key pad on the handle assembly just below the part you pull. i would like to get this on my truck so it looks factory. my question is...where would i get this kind of handle with the key pad...and would it work with alarm systems...any alarm systems...just some systems...if so which ones? has anyone done this before?

also, how hard is it to install remote start alarms...too complicated for a weekend driveway installer like my self? i have some knowledge of wires and that sort of stuff and enjoy wireing stuff and figuring it out...i just dont want to run the risk of messing something up big time...has anyone done one them selves?

thanks for any help or suggestions.
