Not for my Maxima, but for my mom's 00 Accord.

I was reading up somewhere that if you could hook up a car stereo, then you can hook up a car alarm/remote locks.

 

It's quite a bit more complicated than that.

the basics are the same.. pull off a few panels, hunt down the right wires, splice away.

BUT.. the trick is to get the right wires the first time, and do the install in a safe method that won't be prone to problems or loose connections.

basically if you've got the right tools (multimeter, logic probe, basic wire cutting/splicing/soldering stuff), the wiring diagrams for the car, a few hours of time, and lots of patience, then you can do it.
You also need knowledge of how relays operate in order to make sure you get the door lock pulses correct. Different makes of cars use different types of systems that will need anywhere from 1 to 4 relays just to lock/unlock the doors.

but don't just think that if you can plug in a wiring harness adaptor to install a new head unit that you'll be able to install a keyless entry.

 

Clee130,

At one time I would say if you had enough smarts to hook up
a car stereo, taking a shot at car alarms wouldn't be a chore, As stereos have evolved and control systems have gotten more computerized on cars and a "Hack" has more chance of doing damage than good.

More and more cars come with keyless entries and piggy-backing an aftermarket alarm without technical support isn't for amateurs. some require specialized resistor packs or the installation of diodes, not just a simple wire to wire hook ups.

If you were not versed in the installation techniques of a sophisicated alarm system and you successfully installed a alarm, how much protection could that possibly be against theives smarter than you?

Now that you put it that way... Heh heh heh... I guess I should leave it to the professionals...

 

I would just have someone do it. If you buy it from a store, they usually only charge like $50 extra to install everything. If you want a full alarm...if you just want keyless entry, you could try it yourself.
