Hi Zahara, I'm glad to assist you. No. The AC Delco 23122150 is only an ignition lock cylinder housing. The normal practice is to install a new lock cylinder into the new housing. But you can recode a new lock cylinder to your original key by removing the tumblers (slugs) and springs from your original lock cylinder and putting them into the new one so you can still use your original key. Here is how the process normally goes: 1. Disconnect the original ignition lock cylinder from the old housing following the manufacturer-specific procedure, which typically involves rotating the key to a particular position (commonly ACC or RUN) and releasing a retaining tab. 2. If you would like to utilize your old key, you can rekey the new lock cylinder by moving the interior parts (tumblers and springs) of your old cylinder into the new one. This will have the new lock cylinder function with your old key. 3. Mount the newly coded lock cylinder into the new housing.
