Our Rex Key & Security company has been specializing in the car lock industry for almost 100 years. Everyone at one time or another, has locked themselves out; lost their keys or had one stolen needing a replacement lock. Our staff can make a new set of keys for your vehicle.

Replacement Motorcycle Keys

If you need a replacement motorcycle key in Berkeley or surrounding areas, we can help. First you’ll need to remove the ignition/key switch from your bike. If you do not have the proper tools to do this yourself, simply bring your bike to our Rex Key & Security shop and we can do it for you. Alternatively we offer 24/7 emergency service and can go to you. If you plan to take the key to the shop or bring the switch, give us a call with the year and make of your bike and we’ll let you know if we can make the key for you.

Before we hand over the replacement motorcycle key we will ask to see proof of ownership; registration and a driver’s license. It’s recommended that you have some duplicates made before you leave!
