Top FAQs

What happens if I skip disconnecting the battery?

Big yikes! You could fry some electrical components or even get zapped. Always disconnect the negative terminal of your battery before starting any electrical work on your car.

Do I need a new key?

Probably! Most new ignition cylinders come with new keys. If your car has a transponder key (a key with a chip), you’ll likely need to get the new key programmed to your car’s computer. We’ll cover that!

How long will this take?

Plan for a couple of hours, especially if it’s your first time. Taking your time and being careful is way better than rushing and messing something up. The more experience you have, the quicker you will be.

Can I just take it to a mechanic?

Sure! If you’re not comfortable working on your car, that’s totally cool. Mechanics do this all the time. But hey, doing it yourself is a great way to save money and learn something new!
