Advice on how to bypass land rover alarm without fob key

Hi guys
Land Rover Discovery 2003.
I hope you can help me. I took my car in for an oil change. When they were done, they parked it outside and handed me the key. I put it in the lock to open, the lock just rotated! The alarm was flashing. The guy noticed one of the doors wasn’t closed properly. Locksmith got me into the car. The car won’t start. All the lights go on on the dash, the windows are working, it just won’t start. I am assuming this is because of alarm, the car thought it was being stolen and shut down. I don’t have a FOB key or remote.This happened two nights ago.

Here’s what I’ve done so far: I left the battery disconnected, the red side, overnight. Nothing changed, still won’t start.
Made tons of calls, Land rover gave me the four digit code for a Fob and told me to call lock shop, I called all over town, nobody I talked to makes Fobs for Land Rover.
Someone told me I can bypass the alarm by taking out the door panel, there will be something at the back of the lock I can remove, that will enable me to start the car.I took out the panel and found that the lock is broken inside, there’s a bronze rod written r33077 that’s broken. I think that’s why the key is just spinning.
Land Rover said to tow the car in today. I am moving to another state this weekend. I am all packed and serving the last few days of my notice, I need the car asap.
If you know of anyway I can drive this car, I would be so grateful.
Please help me
Thank you

Seriously the dealer is your best shot.
I am very familiar with other European cars of that vintage and it is quite likely bypassing the alarm is not possible.

Ok. Thanks, Rick
