However just bear this in mind, I asked this question while back and here it is copy/pasted for info:-

Q - if I do this and ever have to enter car v the boot then can I open the doors manually from the inside even if the double-locking is activated - thought that was its purpose ?


A - No you can not open the doors from inside if your bat goes and you have the delock you have to get in via the boot and pop the bonnet then apply jump leads or a jump box.

If its cos the remotes broken or lost you are a bit stuffed guess you would have to break the delock off.

When i got my it only had the 1 remote and 1 regualr key so i bought a 2nd remote of Ebay and was easy to program so I have a spare.
