Question for anyone that can help. The remote for my Max stopped working - dead no signal. Bought a new one of Ebay, but can not program it. The computer will not go into programming mode

How easy is it to replace the module in the trunk or am I better off just getting an aftermarket system at this point.

Thanks in advance!

 

I sell nice Viper system with remote start installed for $300
regular Viper alarm $200 installed
