Will this work if the 1971 Mercedes Benz 300 SEL has an aftermarket alarm?

🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Lost Keys
Locksmiths or dealers can: 1) Decode your door or ignition lock to determine key cuts 2) Access your car's key code through manufacturer databases (with proof of ownership) 3) Program new transponder keys using diagnostic equipment.
Key Tip: Consider key insurance for expensive smart keys
Security Systems
This means your car's immobilizer system can't read the key's transponder. Causes: dead key battery, damaged transponder chip, faulty car antenna ring around ignition, or system needs resetting. Try replacing the battery first.
Security Systems
An anti-theft system that prevents the engine from starting unless it detects the correct transponder chip in the key. The chip sends a unique code to the car's computer when you turn the ignition. No match = no start, even with a physically matching key.
Lost Keys
1) Contact a locksmith who specializes in automotive keys or your dealership 2) Provide proof of ownership (registration, title, ID) 3) They'll either cut new keys by code or reprogram your car's system 4) This is expensive ($200-$800) as the immobilizer may need resetting.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
Lost Keys
Yes, a skilled auto locksmith can extract the broken key and make a replacement. They can often do this without damaging the ignition cylinder. The new key will need programming if it has a transponder chip.
Key Fact: Key fob batteries typically last 3-4 years with normal use
