A car key disguised as a screwdriver. This prank will make it look like your car has been stolen by having the ignition punched by a screwdriver, while in reality it's just your normal car keys
Even though this is a harmless prank there's the real possibility of it being taken seriously. So use with caution (or don't do it at all).
Here's a video of it in action:
To keep things accessible I stayed away from welding, opting for a strong epoxy combined with a clever joining solution to combine the stainless steel screwdriver with the nickel covered brass key.
Ready to build your own and get into trouble? Let's make!
Step 1: Supplies
To make your own screwdriver key you'll need an extra set of your car keys, and a screwdriver.
This obviously won't work for newer cars that have electronic proximity or transponder components, or other types of car keys with sophisticated security.
When choosing a screwdriver try and select a screwdriver with a bright colours that looks really obvious, this will help it stand out when jammed in the ignition.
You'll also need a rotary tool with a cutting wheel attachment.
Step 2: Chop Screwdriver Shaft
I used a rotary tool to chop the shaft from my screwdriver. With the handle of the screwdriver securely tightened in a bench vise I slowly worked the rotary tool to cut the screwdriver shaft about 1/4" (6mm) from where it meets the handle.
Step 3: Slot Screwdriver Handle
Mark the key width in the cut end of the screwdriver, make sure the key is centered on the cut shaft.
Transfer the key width to the cut end of the screwdriver with a marker, then use the rotary tool to cut a slot into the screwdriver shaft and into the plastic handle of the screwdriver. This slot in both the metal shaft of the screwdriver and the plastic handle will ensure good contact between the screwdriver and they key and prevent it from snapping out from torsion.
Step 4: Cut Key
The back of the key will need to be cut flat to sit inside the slot. Since we want to wide end to sit in the groove we cut into the handle try and keep as much of the key handle as possible.
With the key securely tightened in a bench vise the back of the key was trimmed flat with the rotary tool.
Step 5: Epoxy Key to Screwdriver
With the key cut with a flat back, and after ensuring that it easily fits inside the cut slot, the key can then be epoxied in place.
Two-part epoxy was mixed and gobbed into the screwdriver slot.
Step 6: Fit Key Into Screwdriver Slot
The key was a tight fit into the screwdriver slot, once the epoxy was applied I used a hammer to tap the screwdriver and key together.
The epoxy was then left to cure completely, making a solid connection.
Step 7: Insert Prank Key
Once the epoxy is cured you're ready to take the new key for a spin!
Have fun explaining to the police that the screwdriver in your car steering column is actually your new car keys :)
