My 2000 Cadillac Eldorado has the same problem—any luck getting the key code?

My 2000 Cadillac Eldorado might finally get back on the road thanks to this.

Has anyone gotten this method to work on a 2000 Cadillac Eldorado before?

Same issue here with my 2000 Cadillac Eldorado, let me know if it works.

This is gold. I’ve been locked out of my 2000 Cadillac Eldorado for days.

🔑 Car Key & Fob FAQ

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

Key Programming
Common reasons: wrong key type for your vehicle, anti-theft system needs reset, low car battery voltage during programming, or the key isn't properly synced. Some cars also have programming limits (only 2-4 keys can be registered).
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
Key Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Security Systems
Not recommended. Bypassing requires specialized knowledge and may violate anti-theft laws. Proper solutions: 1) Get correctly programmed keys 2) Replace faulty immobilizer components 3) Have dealer reset the system if keys are lost.
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 Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
Key Fact: Some insurance policies offer key replacement coverage
