How do you unlock a deadbolt from the outside without a key?

Answered by Edward Huber

Unlocking a deadbolt from the outside without a key can be a tricky task, but with the right tools and technique, it is possible. Please note that attempting to unlock a deadbolt without proper authorization may be illegal and should only be done in emergency situations or with the owner’s consent.

Here is a step-by-step guide on how to unlock a deadbolt from the outside without a key:

1. Gather the necessary tools: You will need a drill, a drill bit suitable for metal, lubricant (such as WD-40), a screwdriver, and a pair of goggles for eye protection.

2. Insert the drill bit into the tip of the power drill: Choose a drill bit that fits snugly into the keyhole of the deadbolt. It’s crucial to use the correct size to avoid damaging the lock further.

3. Apply lubricant: Apply a generous amount of lubricant around and inside the keyhole. This will help reduce friction and make it easier to drill through the lock pins.

4. Put on goggles: Safety should always be a priority. Protect your eyes by wearing a pair of goggles before proceeding.

5. Start drilling: Place the drill bit into the keyhole and gently apply pressure. Begin drilling slowly and steadily, allowing the bit to penetrate the lock tumblers. It’s essential to maintain a straight angle to prevent the bit from breaking.

6. Continue drilling until the tumbler pins fall off: As you drill, you may feel resistance from the lock pins. Keep drilling until the pins break, allowing the deadbolt to turn freely.

7. Insert a screwdriver to unlock: Once the tumbler pins are dislodged, you can use a screwdriver to turn the deadbolt and unlock the door. Insert the screwdriver into the keyhole and turn it in the direction that unlocks the deadbolt.

It’s important to note that drilling a deadbolt should only be considered as a last resort and should be done with caution. It can cause irreversible damage to the lock and may require a replacement afterward. Additionally, always ensure you have the necessary authorization or legal right to attempt to unlock a deadbolt without a key.

Remember, it’s always advisable to contact a professional locksmith if you are unable to unlock a deadbolt or if you do not have permission to do so. They have the expertise and tools to unlock doors without causing damage and can ensure the security of your property.
