Thread: Replacing battery in key.

There are good you tube videos, I did my D4 yesterday and needed it.

Is there an easy way to open the key on my D3 to replace the battery???
Is it just insert a screwdriver/something into the slot on the side and lever open, or is there some other way??
I'd just like to do it without making the key look like its been through a war!

Very good explanation here.

By way of explanation, the D3 and D4 keys are completely different. The D3 uses a rechargeable battery (recharges each time you put it in the ignition) and is supposedly waterproof.
Hence why you have to cut it open, un-solder old, resolder new battery and glue it back together.

I'm damned if I can see where it recharges, but if it does, I won't worry.
Another dumb question(I thought I knew my D3!) - how do you tell if its a rechargeable key? It (and its mate) were genuine new keys from Land Rover when I purchased the truck in 2017.

All D3 keys are rechargeable. From the owners manual, Page 41 -
To recharge the battery, insert the key in the starter switch and start the engine.

It uses induction charging I believe.

Awesome, thank you - case closed!
Enjoy Hawker!
