SOURCE: Mercedes S320 central lock

The Key Fob needs to be syncronised to the car........Try this it works for many Mercs1....ensure the battery in the "Key Fob" is OK............Press either Lock or Unlock button for more than 1 second, the lamp on the fob will light if OK. Change battery if it does not illuminate!  2.....if battery on fob OK.......Re Syncronise the key fob to the car by:.... a brief press on either button twice and within 30 seconds turn Key to position 2 on the ignition lock 
Hope that fixes it...let me know?

I know on the L.H. (previous fuel injection system) models there was a module called a base module that worked as a big overvoltage relay and powered up all the control units for the engine and drivetrain,they had 4 to 6 10amp. fuses in the top and theywould blow fuses and sometimes fail themselves causing no start conditions. I beleive yours is an H.F.M. system. I used to do roadside and i'm also a mercedes benz tech. The first thing I would try would be to put the car in nuetral and see if it starts. the nuetral safety switches of that era are problomatic. next I would check my brake light fuse in the engine compartment fuse box. That fuse also powers the starter relay-even though it doesn't state that on the fuse schematic. Also to answer your question about a lockout relay-yes there is but they rarely cause a problem. I hope I have been helpful

"supplement restraint system" "srs" witch is the airbag system and because it's a c320not all shop's have then software to retrieve the codes. so it will need to be brought into a shop that has the software then they can tell you what is wrong with it. most likely a airbag went bad. or could be a seat belt sensor also. no real way to tell untill you have it scanned. hopefully that help and if you have any more question please ask. good luck
