Alarm after remote start cycle

Recommended Posts

This winter the alarm started going off after a remote start cycle ends.  When the car shuts off (after remote start cycle ends) there will be about a 30 second delay and then the alarm starts going off.  I mentioned it to the dealer service and they suggested trying a different FOB before they started digging into it. They obviously had not heard of the problem before. I tried a different FOB and it made no difference.  I have searched the internet and haven't seen anyone else mention this problem.  I don't have a lot of faith in the service at the dealer, so I am wondering if anyone has any ideas?

I have a 2019 Yukon Denali, and it’s horn starts honking for no reason. Tonight In was standing next to my truck with the door closed, key in my hand and fob hanging from the key ring, for no reason at all, the horn started blaring. Not honk honk honk, but just constant. Wouldn’t stop with me pushing buttons on the remote fob, I had to unlock the door and start it. I left the engine on and Door open as I talked to my employee, and the engine shut off, and horn started blaring again. I had to restart it to get it to stop. The other day it did the same thing but it also would honk when I turned the wheel with the engine and moving forward. It didn’t do it since Sunday so I figured it was  a random issue, but after tonight, I’m going to dealer in morning and letting them sort it out.. trust me if they say they can’t duplicate the problem, I’m not picking the truck back up.

Alright guys.. problem solved. rear defroster plug wasnt making connection. its part of the alarm system as if someone broke your rear glass.

so anyone having this issue its to do with one of the defroster tabs falling off which is pretty common, fix it and the alarm issue goes away.. i just did it and over 50 remote starts with the issue and now its gone!

      Hey all, I have a 2008 GMC Sierra 2500HD 6.0L Gasoline. Remote start is not working.
       
      This sucks a lot for those of us living in Central Alberta
       
      Initially the truck didn't start due to a check engine light coming from my downstream O2 sensors. My catalytic converters were cactus, so I removed them, had the O2 sensors adjusted and the engine light disappeared. That was two weeks ago. The remote start worked for one or two days and then I started having issues with it.
       
      At first the remote start only worked intermittently, maybe once out of every 10 or so attempts and it was random. Then it stopped working altogether. I press the lock button on the fob and then hit the start button. The park lights on the truck flash as if it's going to engage, and then nothing happens. No sounds either coming from it to suggest it's going to start up.  I looked at a few forum posts and dealer recommendations and attempted fixes. This is what I've troubleshooted so far:
       
      I start the vehicle manually, then attempt to use remote start. Nothing. I'm aware it only has two start attempts.
      My lock and unlock buttons both work fine.
      There are no check engine lights or lights of any kind appearing on the dash.
      Hood lever sensor seems to be functioning. No hood open warning on dash. (Still may be a problem but I'd like to avoid replacing the latch and sensor unless it's my last option)
      Oil pressure and coolant temperature are normal.
      There is no extra key or key fob in the truck.
      Hazard lights are not on.
      Vehicle is definitely in park.
      I replaced the battery in the remote. No dice. I do have a now remote on order just in case although it does seem to be communicating fine with the vehicle.
       
      I finally found a blog that suggested that it might be the brake light switch. Apparently this can cause both the cruise control and the remote start to fail if it starts to loose it's marbles. I decided to test out my cruise control and unbeknownst to be me the cruise control will not engage either. So this morning I replaced the brake light switch (which was no easy task). I jumped in my truck to test drive it and it seemed to brake fine and the lights still worked when the pedal was depressed. Cruise control still would not engage (but I don't care as I live in central alberta and don't use it at the moment), but when I returned home, I shut down the vehicle, locked it, and attempted the remote start. It worked!! TWICE!! I was super excited, turned on the ignition to reset it, turned it off, jumped out of the truck and went to attempt it again. Nada. Nothing. No dice. Zippo. I've retried 5 times after turning on the ignition to reset it, and still nothing.
       
      Can someone please suggest where to look next? Any ideas? Anyone had the same drama and found a fix? I don't want to take it into a shop, I know it'll cost an arm and a leg! 
       
      Thanks!

      I have a 2019 Chevy Silverado 1500 and my key fob only has the lock/unlock, and the panic button on it. I saw that the official Chevy accessories page has the key fobs with remote start, tail gate unlock on them as well. If I get one, will I be able to have the dealership program it on my current truck so I can have remote start or is this only for replacement for owners that already have the same key fob?

      Anyone have a check engine light show up then go away and come back? Code uo129 lost communication with brake control module, UO101 lost communication with transmission Control Module. Went to bed with no check engine light, woke up in the morning for work and noticed the truck would not remote start. When I go in to head to work noticed check engine light. After work ran codes. Shortly after getting codes and using google to research check engine light was gone. Went for a drive never came back on. Woke up this morning it was on again. Can anybody relate?

      My Ford F-150 didn't have keyless entry so I kept my keys in during one of my extended overseas trips, using the keypad to get in and my keys always safe. I could never stand the thought of losing my keys 6,000 miles away and having no way to get in my truck and I wouldn't be able to get in my house! I learned it the hard way a long time ago, never again.
       
      I didn't know my Chevrolet came with keyless but it was attached to a fantastic deal I couldn't refuse so I had a dilemma. I could use my phone to unlock my truck so I didn't really need the keypad my Ford had, but I just may install one for $250 at the dealership anyway. That's just in case I lose my phone whilst overseas.
       
      Unfortunately, keeping the keyless fob around the new Silverado will cause battery drainage as the module will be kept active when the keys are detectable. My truck didn't lock when I was at the back of my truck. As one member said, the Hitch Safe wouldn't be good enough and he's right so it was no longer an option. One here suggested wrapping it in aluminum foil and I tried that. It worked very well and realized my Progresso soup can had thicker aluminum so I tried it with the smooth-edge can opener and, voila!
       
      I am very pleased to report my truck did not unlock when I held it inches away from the door. To think I was going to spend $19.99 for a can of Coca-Cola with a secret compartment!

      Now, my question is: if I used my phone to unlock the truck from a distance... how long would the battery last before it dies? Can it do a month?

      Has anyone used the plug and play kit from MPC for remote start? Reviews are mixed but I think my Tahoe would greatly benefit from this since I am up around 4:30am on most days and hate having to run out there to start it and use a second set of keys to lock it.

      Or does anyone know of another company that is fairly easy to install?
