How to get into my 2003 honda accord boot? - 1

Added (1). key won't work, lever won't work and fob won't work… Any ideas

Hi the release catch is in the drivers door jab so just lift it.

As above, key won't work, lever won't work and fob won't work, does anyone know where the keyhole inside the car is for lowering the back seat

If the keyhole isn't obviously on the back deck, I don't know what to tell you. Open the center arm rest, open the door to the trunk, pull the green release lever under the deck to lower the back seat, then crawl into the trunk.

The backseat release is in the trunk. If you can't reach through to get it then you will need to call a locksmith.
