What OEM actually means
OEM stands for original equipment manufacturer, meaning a key built or branded by the same source the automaker uses. Aftermarket keys are made by other reputable manufacturers to work with the same vehicles. Both can be high quality, and both must carry the correct chip and be programmed to your car to function.
The dealer sells OEM keys by default. A good mobile locksmith can supply quality aftermarket keys and, for many vehicles, genuine OEM keys as well, so the choice is not simply dealer versus off-brand.
What actually matters for your car
What makes a key work is not the logo on it but whether it has the right chip for your vehicle and is programmed correctly. A properly cut and programmed aftermarket key starts and locks the car exactly like an OEM one. The immobilizer only cares that the key presents the identity it trusts.
Where quality does matter is durability and fit. A cheap fob can feel flimsy or have weaker buttons, which is why we use reputable keys and stand behind them. We are happy to use OEM when you prefer it and it is available for your model.
Cost and choosing the right route
OEM keys generally cost more than aftermarket, and the dealer route adds shop labor and ordering time on top. A locksmith can often offer both options and let you decide based on budget and preference, usually faster and at a better total price. We quote your exact year, make, and model before any work, so call us for a real number.
If you simply want a reliable working key without paying dealer rates, a quality aftermarket key from a locksmith is the practical pick. If you specifically want OEM branding, ask us and we will source it when it is available for your vehicle.
