How accurate is VIN key cutting — is there any risk the key won't work in the door or ignition even if the cut data is correct?
VIN key cutting is highly accurate when performed with professional decoding equipment, as the VIN maps to a specific key code on file for most vehicles manufactured in the last two-plus decades. At Sundial Locksmith, we cross-reference the decoded cut with known databases and verify the result before programming, which keeps error rates extremely low. Call (480) 525-7778 if you need a VIN-based key and we'll be straightforward with you about what to expect for your specific make and model.
