The box under the left side seat is the 'central locking unit' The antenna wire for the remote may not be connected securely.
Check this post and the thread it was posted in. The round gold colored connector is where the antenna connects if you have a 3 button remote.
***Note: Do not put your key in the ignition with the seat removed. It can cause an airbag fault.***

The cars with two button remote and M531 module have the coax run through terminals the blue connector. Either way, you have the coax antenna in the harness, but on the M535 they split it out and put it through a proper RF connector. So, I would say that you have an M531 alarm/immobilizer module in your car.
A picture is worth a thousand words, so here you go.
