X308 XJR Flat battery- how to open boot

[Zippyworld]

Hello

Advice please, I have a duff battery and cannot access the boot.

How can I do this ?

Which battery should I get to replace it ?

Thankyou

If it's like the x350's you can unlock the boot with the key from underneath the plinth on the boot lid.

Hi

Thanks for your reply, there is a key hole in the boot of a 308, its none functional due to the flat battery.

The key manually operates the latch via a lever so should not rely on battery power to operate. That is precisely the reason why it exists as a backup.

It may be stiff due to never having been used, but it's there to be used so go for it...

This is weird then, I have used the key before ( years ago )
Its the first thing I tried and its not doing anything…

Try some WD40 in the lock, worked for me.

Yup, WD40, wiggle the key and give the boot lid a few hard thumps.

Or you can power up the car with jump leads on the +ve terminal under the bonnet and engine block and unlock with the fob as normal and if that fails then there's a technique where you remove the rear plate and drill a hole in the boot lid to access the locking motor actuator rod.

Video for that on Utube IIRC.
