viper 5900 2 cars on one remote

Hello all,

I am a consumer that is trying to figure out how to control two cars on one Viper 5900 remote.

I have two cars, each with the 5900 installed.  The installer tried to program the remotes to work the primary car as well as the secondary car, but it seemed to just default to the remote controlling both cars simultaneously.  I was told it could be done and that was the reason that I purchased the systems for both cars.

Does anyone know how to do it?  I get the impression the installer has no clue.  Is this something that a consumer can program?

I also have a question about crank time.  It seems like mine is too short on my car (it won't turn over on a cold start, only if the car has been warmed and running using the traditional method.  Is there a way to change the crank time?

Thanking you in advance.

I didn't have an install manual when I posted the question.  I did some research and found the manual on your website.  Thanks for making that recommendation.

I took my cars back to the installer (as I am a consumer).

The installer increased the crank time and also programmed the individual remotes to work with the other car.

From what I understand, different keys are being used on a different channel which allows me to arm and disarm the second car.  I didn't try to have the remote start feature enabled on the second car b/c that looked more difficult.

So, it can be done ladies and gentlemen.

Thanks again for all your help.
