Anyone try this on a Izuka T125B with push-button start?

Trying to avoid reprogramming costs for my Izuka T125B. This is a lifesaver.

Same issue here. Let’s hope it works for my Izuka T125B.

Does this method work for the Izuka T125B models from 2010 onward?

My Izuka T125B refuses to start. Could be the key code—trying this fix.

🔑 Car Key & Fob FAQ

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

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.
Key Tip: Avoid exposing key fobs to water or extreme temperatures
Lost Keys
Costs vary widely: Basic keys: $50-$150, Transponder keys: $150-$300, Smart keys/fobs: $200-$800, Dealership replacements typically cost 20-50% more than locksmiths. Emergency/lockout service adds $50-$150.
Key Fob Issues
Sometimes. Broken buttons can often be fixed by cleaning or replacing the button pad. Cracked cases can be glued. However, water damage or circuit board issues usually require complete fob replacement. Reprogramming is still needed for replacement fobs.
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: Avoid exposing key fobs to water or extreme temperatures
Cost & Options
Locksmiths are typically 30-50% cheaper than dealerships for key replacement and programming. However, some newer models (especially luxury brands) may require dealer-only programming tools. Always get quotes from both.
Key Fact: Key programming typically takes 15-30 minutes for professionals
