When you need a new key or fob, you'll often have a choice: a factory (OEM) part or a quality aftermarket one. Both can work perfectly — the right pick just depends on your car and budget. Here's the honest breakdown.
What "OEM" and "aftermarket" really mean
OEM keys are made by (or for) your vehicle's manufacturer — identical to what came with the car. Aftermarket keys are made by reputable third parties to the same specifications, usually at a lower price.
When I'd recommend OEM
- Newer or luxury vehicles where aftermarket parts aren't yet reliable.
- Push-to-start smart keys on certain makes that are picky about the part.
- When you simply want factory-identical, no question.
When aftermarket makes sense
- Most common makes and model years, where good aftermarket keys perform identically.
- When you want to save money without giving up reliability.
- Spare keys and basic remotes.
How I help you choose
I carry both, and I'll tell you straight which is the better value for your exact car — I'd rather you have a key that works for years than upsell you. Either way it's programmed on-site and backed by my 90-day warranty. See key fob replacement or car key replacement, and the cost guide.
