My 2009 GMC Sierra remote engine start has a problem?

[Thamer]

My 15 months old GMC Sierra has some difficulties starting using the remote key. although, when I lock or unlock doors the remote key works perfectly! but when I try to start the engine via the remote key, it starts hardly after 3 or 4 trials.
An observation: when I try to start engine from long distances, it usually works. while trying within 20 yards won't make it from the first time.

Is it the remote key battery? or it could be a receiving problem?

Likely user error...

If the remote works on the door I would not think its the battery. My last 2008 worked for almost 3 yrs till I traded it in May and never had to replace a battery. Occasional the remote start would not work from in the house but if I pointed directly at the truck it would. So if you are not pointing it in the direction of the truck it may not be getting a strong signal. That's all I can think of.

I would suggest having your vehicle checked out by your local dealership. They would be the ones best able to diagnose the issue and see if there isn't something wrong with either end of the remote start system. You should still be covered by the 3 year 36,000 mile bumper to bumper warranty so you should be covered for the fix, under normal circumstances. I hope that helps.
