Why make a spare before the original key is lost?
A spare gives you a backup if the main key is lost, damaged, or locked inside the vehicle. Depending on the vehicle, adding a spare while a working key remains can also be simpler than handling an all-keys-lost situation later.

What Makes a Good Spare-Key Appointment
- Bring the working key: If one exists, have it available during the appointment.
- Vehicle details: Year, make, and model help confirm the correct key before arrival.
- Choose your key type: Ask whether you want a full remote/smart key or a simpler compatible backup option.
- Test before leaving: Lock, unlock, starting, and emergency-blade functions should be verified before the job is complete.
For the fastest compatibility check, call or message Heatwave Locksmith with the vehicle year, make, model, whether you have any working key, and whether the vehicle uses a traditional ignition or push-button start.

Can I get a cheaper backup key without buttons?

Can you make two spares?
If compatible keys are available and the vehicle supports them, ask for multiple keys when scheduling.
Will a copied blade alone start the car?
On transponder-equipped vehicles, a mechanically cut blade alone may not authorize engine starting.
