You could try connecting a battery charger to the generator's output terminal since the battery is connected directly to it. Be extra careful not to short that connection to ground (chassis of the vehicle)!
After the battery has been charged enough, use your remote or the button for unlocking the trunk.
You may also look up for a large positive terminal in the engine compartment and connect the charger there.

The 1994 xj6 sedan. The trunk should be opened by the key unless you have green keys only (valet keys).
If this is the case then open the hood and on the firewall there is a black plastic square box with a + sign on it, lift up the plastic cover, connect your jumper/charger on a low boost and this will give you enough power to push your remote trunk release switch.

Posotive can be found in hood driver side next to fuse box. It is a small rectangle box. You can hook negative to any solid ground on the car.

When was the car wrecked? I say that because this lever is hooked up to a thin cable and goes all the way to the back of the car. A technician might have not secured the cable end correctly when the work was done. . Otherwise, the cable *could* go bad on its own, even though this would be pretty rare.

In this scenario, faced with a broken key in the trunk lock, a dead battery, and a malfunctioning remote, several steps can be taken. First, attempt manual key removal with tools like pliers. If possible, jumpstart the car battery to restore power and potentially operate the remote. Check for an internal trunk release lever in the cabin. Alternatively, seek assistance from a locksmith or automotive technician for safe key extraction and trunk access. Once opened, retrieve the spare key for future use. Prioritize caution and safety throughout the process.
