Is there a way to open the trunk of a 1997 Jaguar XK8 from the inside if you've locked your key in the trunk?

Answer 1

Remove the bottome seat and then the back as the bolts that hold down the back are hidden by the bottom. You will be able to get into the trunk from there. Also you can go to the dealer and they will make a copy for you for around $100

no, no, no, no!

RAISE THE HOOD, ON THE DRIVERS SIDE IS A COVERED POLE NEXT TO THE FUSE BOX.

ATTACH RED JUMPER CABLE TO THE POLE, AND BLACK TO A GROUND. WALLA!

Sorry, you can't get to the trunk from the back seat. The fuel tank is in the way. If you don't have another fob you can always just press the trunk open button next to the steering wheel, but I'm assuming that either your battery is dead or the security system or valet mode is armed. If the battery is dead, do what the prior poster said, attach jumper cables to the post under the hood. If the security system is armed or it's in valet mode, take off the inner door panel on the driver's door. Then you can reach into the door and manually manipulate the latch mechanism to make the car think that you inserted the key into the lock and unlocked the car from the outside. You'll have to take the little push-rods between the lock and the latch off, but by simulating unlocking the door you'll take the car out of valet mode and turn off the security system. WATCH OUT THOUGH! The window is going to drop if you "pretend" to turn the key for too long, and it might chop off your hand.
