Pricing, Explained
No two jobs are identical, which is why we quote each one on the phone first. The main factors:
- Whether a working key is available or all keys are lost
- How many keys you want
- The type of key (basic, transponder, remote-head, flip or smart key)
- The make and model
Compared with the dealer, most drivers save both money and time — and skip the tow. We would rather give you an honest number on the phone than surprise you on arrival.
