Alarm and Keyless Entry or just Keyless on LT?

Recommended Posts

Recently bought a 2015 1500 Crew Cab 4x4 LT with 1LT plus package. Seems fairly nicely equipped but noticed that when locked with the key FOB the light sensor/ alarm light on the dashboard does not light up or flash. Also noticed that if I unlock the door with a key and open the door no alarm sounds (I believe I read that this should set off the alarm). Is it really possible that the keyless entry doesn't include any sort of alarm or does it seem like it just isn't working right? Figured WT model may be Keyless Entry only but no alarm on LT? How do I know if there is supposed to be an alarm or at least a light that blinks when the truck is locked?

In my experience w/ other brands of vehicles, I do know that some keyless entry systems are just that - keyless entry only. My 2015 LT does have an alarm w/ the keyless entry.

Does anyone else have an LT that doesn't have an alarm built into their keyless entry system?

LTZ71 - Keyless entry/w/alarm was in All Star Edition option package.....the theft deterrent system is standard only on the LTZ

Check your RPO list...For example


AU0 is keyless entry only

AU3 side door electric

AP3 is keyless entry with remote start

AP5 is keyless entry passive

and so on. This is mine




Also there is an option where you can add delay for the alarm to sound after you unlock the door with the key to give you time to reach the ignition.

      I bought the 17 GM shock sensor to add to the factory alarm on my 2017 Sierra SLT.  The dealer said it will not work on my truck because I do not have AUO code and that code was eliminated by GM in 2016.  Is there anything out there to add a shock sensor to the factory alarm?

      I have a 2017 Silverado Work Truck. Came with Factory power windows and power locks. It did not come equipped with a keyless entry system from the factory. It does not have any of the modules to add remotes for door lock entry or remote start.  Does anyone know of a kit to add these features to my truck?

      Hello, I have a 2001 GMC Sierra 2500HD, the keyless remote receiver seems to be going out on the truck because i notice it is very selective on when it wants to work, from what distance, and every other factor in general. I even replaced the battery in the original remote and have reprogrammed an identical remote to my truck and it still acts the same. I opened up the dash to find the keyless entry receiver and have the part number #15732806 yet trying to order a new one I come to have found out that it is discontinued and cannot find one online to replace it with. My question is, can I get another keyless entry receiver from say a 2005 or 2007 or 2003 or any other suv/truck from GM and plug it in and just re-program the remote to the receiver, or is there something else I can do to get a new receiver even though the part is discontinued, or basically what are my options?

      Hey, i'm new to forums. Not sure how to search for my problem..sorry if a repeat.     
      I can't seem to find in the manual and running through all the vehicle settings on 2019 sierra denali.
      When i approach the truck with keyfob in my hand, and push the handle button, the lights flash but nothing unlocks.   
      There is an option about proximity entry: off/driver door or all doors... I have it on all doors.   
       Now the damn thing worked fine for the first 2 months...this stopped working 1 month ago.
      Anyone experience this? How to fix?

      I just picked up a 99 K1500 GMT400 and I didn't get a key fob, just keys. Did this model come with remote keyless entry? I would check the codes for the AUO code but truck is getting some suspension work so I don't have it readily available. I know I could add aftermarket RKE but it would be nice to just buy a couple of fobs and be done with it. Thanks so much!
