The "Programming" Problem
All OEM fobs need to be programmed to the car by "teaching" the immobilizer to identify it. This process requires the vehicle PIN code and the ability to navigate a series of timed ignition key strokes. This takes practice, and the alarm can be triggered, complicating matters. Even with practice, many 993's aren't able to program fobs due to aging ignition switch contacts.
Many turn to specialty shops for programming. But this comes at additional cost and significant effort by the owner to remove and reinstall the seat, security bracket, and immobilizer—not to mention the risk of damage and vehicle downtime. Faced with these obstacles, many risk driving without a backup.
What Makes the F 2 Different?
When you add an OEM fob using the factory procedure, you are pairing it to the immobilizer. When you add an F 2, you pair it to another fob. By learning from a fob that’s already been through the programming process, the F 2 doesn't need to go through the process again and you'll be up and running in seconds.
Setting up an F 2 couldn't be easier: simply hold the F 2 and a "donor" fob (one that's paired to the car) next to each other and hold both buttons down until the LED on the F 2 starts flashing. That’s it! A 10-second hassle-free backup:

The F2 is powered by a lithium coin cell. This improvement eliminates the leaky 12V alkaline battery and finicky terminals that can corrode and loosen. The lithium's 10-year shelf life and 30,000+ operations promise a long life and easy maintenance.
How do I use the F 2?
Just like the OEM fob! All you need to do is "select" the one you want to use by pressing it 3 times near the car. Once selected, the F2 works just like an OEM fob: one press to lock, one press to unlock. You only need to do this if you switch fobs. You can switch back and forth as often as you like, but it’s really optimum for situations where one fob is the "primary" and the other is the "backup".
