Does anyone know if this works on push-start SWM Varez 400s?

I think my SWM Varez 400 has the same issue. Good to know I'm not alone.

🔑 Car Key & Fob FAQ

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

Key Fob Issues
This typically indicates: weak fob battery (replace first), damaged fob antenna, or issues with your car's receiver (often in the door handle or rearview mirror). Environmental interference from other electronics can also reduce range.
Key Programming
Some vehicles allow DIY key programming using specific sequences (like turning ignition on/off with original keys). However, most modern cars require specialized equipment only locksmiths or dealers have. Check your owner's manual for your specific model.
Key Tip: Consider key insurance for expensive smart keys
Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
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
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 Fact: Key fob batteries typically last 3-4 years with normal use
