Push Down and pull on the gas cap release on some cars if you push it it opens the trunk and when you pull it it opens the gas cap
I"ll go w/ thebax. Usually on most econoboxes, trunk release (if equipped) is on L side of drivers seat on floor, next to gas-cap door release.
If you've looked really hard, maybe you don't have one. Just go to the trunk and open it. If you live near the dealership, you could ask them, or give them a call.
If it's not on the remote you just use the key! It's not a Lexus.
I have a Hyundai Elantra 2001 and I cant find my trunk release for my car! I have a hood release and a gas lid release, but I cant find the trunk release. Can anyone help?!
