Comprehending the Flip Key Mechanism
A flip key operates on a relatively simple mechanical concept. Inside the plastic housing, the metal key blade is connected to a swivel base. A small torsion spring is positioned in between the swivel base and the fob real estate. When the release button is pushed, the tension kept in the spring is released, rotating the blade into the extended position.

Step 4: Installing the New Spring
This is the most technical part of the repair. The torsion spring should be "pre-wound" to create tension.
Place one end of the spring into the slot in the key blade base.Place the other end into the designated hole in the fob casing.Rotate the key blade (generally one full turn counter-clockwise) to wind the spring before snapping the casing halves back together.Step 5: Testing and Reassembly
Hold the halves together and test the button. If the blade turns out powerfully, the tension is proper. Re-install the screws and change the logo sticker label.
Comparing Repair Options

4. Why is my key still not flipping after I set up a new spring?
This is generally caused by insufficient stress. Many flip secrets require the spring to be wound at least one complete rotation (360 degrees) before the case is closed. If it still does not flip, guarantee the spring legs are effectively seated in their notches.
5. My fob housing is glued shut. How do I open it?
Some makers (like Ford or Land Rover) use "clamshell" fobs that are ultrasonically welded. These can not be opened without breaking the plastic. In these cases, it is normally much better to purchase a replacement "empty" shell, cut the old one open, and move the electronic devices and blade to the new housing.
