I have a 2011 Rieju RS2 Pro 125 Black, will this method work for that year?

Appreciate any advice—my Rieju RS2 Pro 125 Black won’t recognize the key.

🔑 Car Key & Fob FAQ

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

Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
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.
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.
Key Tip: Consider key insurance for expensive smart keys
Lost Keys
Dealerships can often cut keys using your VIN, but will require proof of ownership. This only works for original factory keys - aftermarket or previously replaced locks won't match. The key will still need programming to start the car if it has a transponder.
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 Tip: Newer cars often require dealer programming for first key replacement
Key Fact: Some insurance policies offer key replacement coverage
