Remote Issues
So I've been having an issue as of late with the remote I use every day. Both driver and passenger door handles won't lock or unlock the doors with keyless go. When trying to unlock the doors with the handle when the vehicle is locked it says "key not recognized" in the cluster and when trying to lock the doors when the vehicle is unlocked with the handle it says "key detected in vehicle". The car does start with the push button on the shifter. Also, when the doors are unlocked and I press the lock button on the electronic trunk, it comes down and closes then unlatches and pops back up, but it locks the doors still. Or, if the doors are already locked, and I press the lock button in the trunk, the trunk comes 3/4s of the way down then goes back. It also says "key detected in vehicle" when attempting these. The regular electronic trunk button works just fine to close the trunk. I tried with my second key and the second key works perfectly fine.
As well, with the first key, it has some kind of battery drain issue. I have tried 3 different brands of batteries. The Chinese cheapy ones after a month of keyless go use, the cluster starts saying low battery and the LED won't even light up. With GP branded batteries after 2 months or so it starts having the same issue. I bought a pair of Duracell ones in the store over 2 months back and so far so good, but every once in a while it says low battery in the instrument cluster. Is the key just bad? What would cause an issue such as this?

Just a guess, but I suspect that you have a bad antenna. Maybe the ones in the doors are bad? All of the antennas can detect the key when it's within a few feet of the vehicle, but it triangulates the position based on signal strength. If one or more of the antennas is bad, it can incorrectly triangulate the position making the system think the key is inside the car.

Ah alrighty well i actually don't even use the keyless go feature that much so no biggie. I was wondering now if there's a way to remove the keyless go part from the remote chip (like if it's a single coil or something) that way to stop it from draining the batteries so fast. Couldn't find any pics comparing the regular key chip to the keyles go version one
