Hey y’all

I was wondering should I get a key fob with or without a trunk release button?
i found out that My 99 blazer has AU0 that means i have the RKE system right?

 

I found that if you have the button on the back hatch, you only need three button as it unlocks as a door.

not sure if that helps...

 

my truck does have the hatch button

 

You can get and should use a 4 button FOB, Its extremely useful because the rear glass opener button fails pretty often due to the contacts getting jammed with carbon. and its a right bitch to fix
