Default Unlock question

I just bought this 2016 corvette about 2 weeks ago and one of the remote keys will not work at all. I replaced the battery and it still doesn't work. I also have another problem. I can't get my key to unlock the hatch from under the rear bumper. It will turn the cylinder fine but doesn't unlock (open) the hatch.I was trying to check both keys to see how to access if the battery was dead and neither will open the hatch. Any ideas ? Thanks in advance.

I need clarification...

1 key works the lock but the other key does NOT work the lock? Is that what you are saying?

What battery did you replace?

Are you saying that 1 remote will not allow you access to the driver's door and start the car?

Neither key will unlock the hatch when you turn the cylinder under the bumper with the actual key.

Ok, that sounds like a trip to the dealer for the lock cylinder.

So both FOBs give access to the car and start the car? Only problem is the key function won't open the rear?

Double check that the new fob battery is installed correctly. If it is you may have gotten an old or defective battery. Try a good (tested) battery.

The rear key is hard to turn and takes some effort. There's a linkage or cable between the rear lock cylinder and the trunk lock that has probably come loose - not easy to access.

Good luck!

You may have to shoot some lock "graphite" into the lock to loosen it. Put some on the key and insert after spraying.Watch it, it could be a bit messy

I use lock deicer rather than the graphite. The deicer has some lubricant in it. The lock deicer is 79 cents at WM now on clearance.

Try pressing down on the hatch when turning the key to relieve pressure on the lock.

you have to use a lot of preassure when turning the key then it will pop.

One of the FOB's work correctly and one does not work at all. I replaced the battery and it didn't help. The key cylinder turns about 1/4 turn but doesn't unlock the hatch. Should it turn more than 1/4 turn?

I'd get ANOTHER new battery for the non-working FOB. I'd also make sure that you didn't put it in upside down.

1/4 turn should do it with the key. I'll post up a video in a second.

Thanks. There must be a problem with the cable or linkage going to the trunk lock since mine will turn but not unlock.

With all the dirt these cars kick up around the rear fascia from driving, it would have made sense to have designed a plug or cover on the key way opening - it cant be good having miles of driving debris going straight up there?

I had the same problem. The cable is to long. Inside the car take the back panel off. near the trunk latch is a little box. Its the cable linkage for the trunk. It runs from the key hole to the trunk latch. On mine I just took one end of the cable fitting out of the little box. That was enough to get mine to work. No cutting.. easy fix..

Update:
I took my car to the dealer & the problem with my latch not opening was the piece connecting the lock has come disconnected.

Thanks, good to know. Was there a clip not locked or is it a stupid connection without any security to hold the cable in place?

You bring up a good point. We use the rear hatch key very infrequently. Perhaps putting a small strip of tape with a buddy tab on it to keep dust out wouldn't be a bad idea? All this talk of using the key has me wondering if mine actually works! I've only had it for about six months and haven't had to use it at all!
