Plastic head on master key cracked (w red dot)

All my square keys have red dots which are master keys.

I used crazy glue but it still cracked... multiple times. I didn't want to replace mine, it came with a red dot originally, but the replacement parts from the dealers and other vendors like performanceproducts.com had plastic heads without the red dots.

Where can I get the replacement plastic head WITH red dot? Did other W124 come without the red dots? Why did they get rid of the red dots? Cheers

I have heard that the key with the Red dot is the master. On my car, the original owner took delivery at the factory in 1987 and shipped back home to Phoenix. When I picked up the car a few weeks ago I got 4 red dot keys and the valet key?

So where do I get the plastic cover with the red dot?

The square head key is a master and round head only door locks
and ignition.

The red dots used to mean factory alarm. The did away with them
because at some point they all had alarms.

Try e-bay. Or some older dealer may have NOS key heads.

my low mileage 300E 2.6 came with one round key, one square key with red dot, and one square key without red dot, all keys look original.

I was unaware this car had any sort of alarm.

Leave your drivers window down.

Lock the car with the red dot key.

Wait 20 seconds or so, pull up the lock knob and open the door.

Alarm should go off.

Factory alarms have been around since the early to mid 80's
