Has anyone tried their emergency key? 2019 terrain

I decided to try the emergency key for vehicle entry if the battery is dead. Be VERY careful if you do this. It's very easy to scratch the paint near the door handle as the key needs to be inserted from below at an almost vertical angle in order to pry off the plastic cover before the key can be used. When installing that plastic cover after opening the door,care must be taken to follow the instructions in the manual exactly. If you put the cover back on starting from the front, you'll never get the rear snapped in place and you won't be able to unclip it from the front to try again. This is something you would not want to have to do on a cold day.

Hmm, sounds to me you learned the hard way. Thanks for sharing and I hope I'll never have to use the emergency key.

I did find a useful hack.. On the denali (not sure about other trims) there is a small plastic oval cover directly over the key hole. It can be pried off using a thin flat blade screwdriver.This cover is part of the larger cover the manual wants you to remove.There are three plastic clips that hold it and there's a good chance of breaking one in the process however it is far preferable to break that little oval piece, or it's clips than the entire key cylinder cover. You still have access to the key hole by removing this small trim cover instead of removing the entire cover. As a bonus, you don't risk scratching your paint trying to pry off the entire cover. If you break one of the oval cover clips it could simply be held back in place wih a little RTV silicone... I have had a dead battery with the wife's BMTroubleyou in the dead of winter and there was no way to gain entry to the car w/o the emergency key and then you could only get in via the trunk. Since we live in N. Michigan and winters can be quite brutal, I wanted to practice using the key on the new terrain before I HAD to actually use it in when it was -20F . With all the electronics on this car, I can see a dead battery happening easily. Fortunately it appears GM did not cheap out on the battery. It's a quality AGM 70 amp hour 700CCA battery. If you want to hear dead battery stories on new cars, check out the Subaru Ascent forums. Those guys are doomed. First of all Subaru supplied a bottom shelf battery and secondly anytime the hatch is open there's a 4 amp draw on the battery until it is closed.
