I think I have confused some people so let me try and reword what im actually trying to do or find out. ok My truck does not have factory keyless entry but it does have power windows / power locks. It also has the tire pressure monitoring system. the vin number is: 1GTEC19X88Z151999 the dealership told me that if I buy the keyless entry module that they didn't know if it would work or not.

All Vehicles - 2008 - GMC - Sierra 1500 - WT - ELECTRICAL - BODY ELECTRICAL - KEYLESS ENTRY COMPONENTS - RECEIVER GMC Genuine Factory Part
Part Number: 20803736

RECEIVER Silverado, Sierra; w/o Remote Start


Fits 2008 GMC Sierra 1500 WT


im trying to find out if this will work on my truck it says it will but the dealership says they don't know which I agree is stupid.

If this vehicle was equipped with Remote Keyless Entry from the factory, the RPO on the Label should be AU0 (A-U-zero).

Need some tips on whether I shud bore out my cylinder heads 96mm or 99mm ls1??
