Possibly, if it's dropped the battery low enough. Think you need to enter the EKA.
Do you have the EKA? If so, you can enter it via a series of lock/unlock turns of the key in the drivers door PROVIDING the switches are all working.
Is this diesel or petrol, there are some differences in how the alarm/immobiliser system works on the different engines.

I've disabled mine for now as it spends long periods not being used and I got sick of having to get the book out to find the eka and enter it.
Often, there's enough juice to start it once the eka is entered but it got low enough to loose the eka. I was quite surprised that it happened like that.

14.5V charging is right for the petrol.

Fob, no idea. Button on fob? Or fob battery?

Fully charge your battery, then try again. Having the tailgate open has stolen the amps out of the battery.

Don't forget the white block connections at the bottom of the A posts behind the kick panels, mine were corroded so I cut them out and soldered the wires.unlikely but possible, mine was standing for years.

Thanks for all the suggestions hope your right Rick the pick seems the cheapest option I've used the car today and all been good with fob but will replace batteries just in case got to go to Scotland nxt week in the car with a trailer so don't need any problems on route fingers crossed
