Have you ever been locked out of your car or lost your keys? It’s frightening, and you need a car key replacement.
As someone who’s helped countless folks get back on the road, I know firsthand how stressful a lost or broken car key can be. At 770 Locksmith & Doors, we’ve seen it all – from basic metal keys to fancy electronic fobs that do everything but make your coffee!
Car key replacement doesn’t have to be expensive or time-consuming when you know your options. Let me walk you through what you need to know about getting those keys back in your hand without breaking the bank.
Understanding Different Types of Car Keys and Fobs
The world of car keys has come a long way from the simple metal keys of yesteryear. These days, your vehicle might use anything from a traditional key to a high-tech transponder or smart key system that talks to your car’s computer.
Basic metal keys are the simplest and least expensive to duplicate. Then there are transponder keys (those plastic-headed ones with a chip inside) that send a signal to your car’s ignition system. Getting fancier, we have proximity fobs that let you start your car with the push of a button while the fob stays in your pocket.
