Remote start/keyless entry install?

[porksoda 10+ year member]

Well I found a pretty decently looking remote start/keyless entry system for sale.

Its sounds like a pretty good deal at $50 shipped.

I have been wanting something like this for my girlfriends 1998 Nissan Altima(automatic).

The car has power locks and windows but she does not have a remote to unlock her doors.

So I am wondering how hard it would be to wire up the remote start and key less entry?

Anyone have any idea if I need any special bypass connectors or cables for this kind of vehicle?

I am pretty good with 12volt so I am thinking it cant be too bad but I dunno if I should take it to a professional shop or try it myself.

Here is the unit found(Avital 4103LX):

Avital 4103LX 1-Way Remote Start System and Keyless Entry

Thanks for the help guys!

i did my own in my 2001 Accord. I used a Autopage RS-900LCD. a nice piece.

i needed a iDataLink bypass for the ignition system. i don't know if your model/make/trim requires one, pac-parts had mine in stock. this is preferred instead of wrapping wire around a spare key.

here was my method:

i started by reading the install instructions a few times until i knew what each wire did and what it needed to see (+12V or switched ground).

then i used a Haynes manual to find each wire tap point in the schematics, and make notes of what wire that corresponded to on the alarm.

then i set aside a weekend, disassembled the interior trim and dash, and set to work locating the brain, running wires to the engine bay (power, hood pin, and siren), found and tagged each wire i was tapping, then loomed and taped all alarm wires (prepped the ones i was routing together) - all before actually cutting or disconnecting anything so the car was still operational. once you get started, don't plan on driving it until you finish.

if you have electric locks, you'll have keyless entry with the new alarm. the system will simply control the door locks. you'll have programming options for driver only or all four doors, one press or two, etc.

after I identified each wire and had my harness prepped, i began the now easy task of making connections - all were soldered and then heat shrink or Super 33+ for the taps. all wires were secured in factory or new wire loom so the end product looked factory.

after you make the connections, comes the programming stage. after that i tested then reassembled the car. i got it done in a weekend from start to finish, but i had a week or two ahead of time studying the instructions and my schematics so each wire tap was correct. as an EE i needed to know the why/how for each connection.
