will it work, dei 555g in a 2006 Chevy Up

I am a strong proponent of DEI products, however this vehicle made me open my eyes to using the bypasskit.com (Omega/Fortin/etc.) products. I used the 556U in both a 2005 Chevy Uplander and 2005 Saturn Relay. Both of the vehicles using the 556U caused the service theft system indicator to display in the driver's information center. I would reset it, relocate the ring of the U and test it, all was fine, for a few days but both vehicle owners would call and say that the indicator kept coming on. I tought the owners of the vehicles how to get the warning to go off (ignition cycle 7 times), but the warning returning randomly was not acceptable. The DEI sheet only lists the U as the option for this vehicle's bypass. I started doing some research and found the GMBP piece, ordered two of them, asked them to bring their cars back, installed the GMBP and have not had a single problem since. Both of these vehicles were done in September of last year, so they went the entire winter without issue. I strongly recommend the bypasskit.com piece for these vans! Just my 2 Cents
