Answers to Common Questions About Car Key Duplication in Newmarket
It depends on your car’s key type (mechanical, transponder, remote, smart key) and whether programming is required. I’ll give you a full breakdown (blade + chip + programming + labor) before doing anything.
Yes—if it’s a chipped or remote key, the transponder chip has to be programmed or cloned properly. I handle that for you so the duplicate works like your original.
Maybe — but there are risks. Many locksmiths refuse to cut third-party blanks because they may be wrong spec, poor quality (which can damage cutting tools), or not suitable. Reddit I’ll evaluate whether your blank is safe to use. If not, I’ll suggest a guaranteed blank I supply.
Usually just minutes at the shop, longer if programming or rekeying is needed. For remote / smart keys, the car’s system may need to be accessed.
No, not under normal conditions. I use precise tools and methods to avoid damaging ignition, blade, or lock. But if the blank or key is low quality or misaligned, there’s risk—so I use quality blanks and calibrate carefully.
Avoid future headaches. Get your spare car key made by the trusted local locksmiths at Locksmith On Demand—fast, affordable, and done right the first time.
