S600 / 1993/ w140
Hi all.
There's probably a 100s of posts regarding this.
But can't seem to find the solution or a procedure, most probably just me not looking hard enough..

So here it goes...
I've just brought a S600 93 coupe, to cut a long story short, was a nice day today so thought I'd take the V12 round town. Stopped for half hour, went back to the car, unlocked the car & open the passenger door the alarm went off, car wouldn't start, made a few attempts at locking it unlocking via the remote and manually.. Then disconnected the battery, but no luck, removed a few fuses, still no luck..
Last resort turned to the RAC for help...
4 hours later....
RAC man turns up I put the key in the door no alarm, switch the ignition on she starts up first time..

Is there away I can removing the factory fitted Alarm and immobiliser??
Don't want to be in a situation where I get complete stuck.

Any help would be great.
