I have a Honda Accord Coupe 2003, recently the truck got stuck and wont open anymore, I can hear the locking mechanism clock when I press the button on the remote and when I pull the lever next to the driver seat but it just wont budge. I tried to fold the backseats to get access to trunk from the inside. But now I have another issue, the key wont turn on the seat unlocking mechanism under the rear window, at first I though it was maybe just stuck as well, but I decided to test the key on the lever lock next to the driver seat. I'm using the master key, the one with the buttons on it, not the gray valet key. Is there any other way i can get access to the trunk or to fold down the back seats without the key?

 

The gray valet key will not open the glove box, the rear seats, or the trunk release.

Does the master key work on the trunk release or the exterior doors?

 

Yes the master key works on the door, only the driver side door has a key hole, passenger side door and trunk don't have a key hole.

 

You will have to access the trunk from the back seat. My TSX is similar to your accord. If I turn the key CCW, the passenger seat will unlock, CW for the driver's side. Try with a little more force to get the lock to release.

 

I tried with a lot of force already, I think if i do it any harder the key will break.
I think that this might actually not be the original key, since it doesn't work with the trunk handle lock either. It might be a copy of the valet key, because when i bought the car, the remote look fairly new, almost no wear considering is a 16 y/o car.

 

Explain your situation to a Honda Dealership, and ask the dealership to cut you a regular key based on your vehicle ID number. Just ask them for a key without an imobilizer, and the correct key should open the seat release, but you couldn't use it to start your car.

 

Will do, thank you. I didn't know you could do that. This is my first car so I'm not very experienced on these types of situations.

 

Yup, key with immobilizer is 70 to 100 bucks, while a key without the immobilizer chip in it is 7 to 10 bucks. I've bought both from the dealer before.
