Understanding the Different Types of Key Fobs
Before looking for a replacement, it is vital to determine the specific kind of technology the automobile utilizes. Not all fobs are developed equal, and the complexity of the device directly impacts the expense and trouble of replacement.

2. Transponder Keys
Introduced in the late 1990s, transponder secrets feature a plastic head consisting of a small electronic chip. This chip interacts with the automobile's immobilizer system. If the engine control system (ECU) does not recognize the special digital signature of the chip, the car will not start, even if the metal key turns in the ignition.
3. Integrated Key/Fobs (Remote Keys)
Commonly referred to as "flip secrets" or "all-in-one" secrets, these combine the remote entry buttons with the physical key blade. The blade often folds into the fob like a Swiss Army knife. These require both physical cutting and electronic programming.
4. Smart Keys and Proximity Fobs
The most innovative version found in modern cars is the smart key. These permit "keyless ignition" or "push-to-start" functionality.

- Pros: Lowest cost for the hardware.
- Cons: The owner must still find somebody to cut the key and program the chip; high failure rate for low-cost aftermarket electronic devices; some modern-day fobs can not be programmed by the owner.
