Hi!

Welcome to the forums! Best place to ask advice on repairs/modifications to your 300E is the Tech Help forum. I've moved your thread there.

These fail all the time on 300Es. That is, all the 20-year old ones are now failing.

An independent Merc mechanic will replace it for you in 2-3 minutes, using special tools.

You have to get replacement cylinder from dealer, providing proof of ownership.

An independent might do this for you, providing a "loaner" cylinder until the correctly-keyed cylinder arrives.
