The situation.
Remote buttons, an immobilizer chip and proximity starting can be separate functions. A fob that unlocks the doors may still fail to start the engine. A worn battery can also mimic a more complicated problem.

Describe what still works and what has stopped. We review the vehicle and part details, explain whether your supplied remote is a candidate and confirm programming availability before accepting the job.
Questions about key fob programming.
Can you program a fob I bought elsewhere?
Sometimes, if the part is compatible and reusable for the vehicle. Availability is assessed before work is agreed; purchasing a remote does not guarantee it can be programmed.
Does a fob battery change erase programming?
Many remotes retain their programming during a battery change, but behavior varies. Follow the vehicle owner’s manual and describe the symptoms if it still fails.
Can I copy a smart key just by cutting the blade?
The emergency blade is usually only one part of a smart-key system. Engine authorization may need a separate electronic process.
