Hi,

I had the same problem when i owned my LS.

Lexus wanted around £230 for a new replacement boot part that talks with the key remote.

From what ive read the range is not that good with the key remote anyway.

You would be better off having a aftermarket alarm fitted,that should be able to lock/unlock the doors and maybe even the boot.You might also get a discount on your car insurance.

The price of a alarm fitted should be around £300 all in fitted.The car would also be more secure than the factory alarm.
