I got a 2g gs300 and i got an aftermarket alarm installed. I've got the bypass module for it. Now my question is, do you need a 2nd key to get the remote start to work? The installer said he needs to program it with 1 key in the ignition and the main to program. The car wants to start but he says it won't till i have the 2nd key. Does that sound right?

 

He probably has the cheaper version of the bypass module. Those require a key to be hidden away somewhere in the car. DEI makes another bypass module that's a little more money, about $30-40 for that one. It can save the transponder code into the module and it send it to the car's ecu when the remote start on the alarm activates the module.

 

I also used the DEI module, just make sure whoever is installing it solders it and doesn't try just using standard connectors.

 

That was a concern just before I got my Viper alarm installed but the installer did use the module from DEI so another key was not needed.

 

+1..............

 

 

for our car the new modules whether from dei, fortin, or idatalink do not require a key the transponder code is saved to the module.

 

ask them for the black box bypass module so u dont have to sacrifice one of ur keys.

 

i had the old bypass module on mines for like 3ys untill i upgraded to the newer dei one last year..im glad i did that too

 

Does anyone have a part # for this module that saves the code?

 

I got the new dei module. Now, what is the installer doing wrong? What can i tell him. Cuz for some reason, it still won't start.
