Just joined this forum. I find these forums to be helpful and I like getting answers from real people who have real answers. I just purchased a 2008 suburban LTZ for the wife and kids and was trying to find out about a product I thought looked interesting. The Lockpick from coastal tech. Seems they have very poor customer service but I find their products have mixed reviews from glowing to lower than garbage. Please sound off and tell me what you guys/gals think about the product and company and provide me some insight on the GEN 4 vs GMX 320. What is the diffrence and will they work on 2008 models as advertised. additionally does anyone have a phone number so I can call them.

 

Try posting your question on the Tahoe forum. There has been some talk on the subject over there.
