Hoping someone can confirm this works for a newer Ultra Low Down.

This trick worked for my buddy's Ultra Low Down. Giving it a go myself.

Been stuck with my Ultra Low Down for weeks. This might be the fix.

Following this for my Ultra Low Down. Please update if it works!

Thanks! This could save me a trip to the dealership for my Ultra Low Down.

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: Store your key code separately from your keys
Cost & Options
Some comprehensive auto policies cover key replacement, often with a deductible. Homeowner's insurance may cover keys lost away from home. Always check your policy details - coverage varies widely. Claims may increase your rates.

Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
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
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
Key Fact: The average driver will lose 1-2 car keys during ownership
