## 🚗 What Is a Key Fob?
A **key fob** is a small electronic device that communicates with your vehicle’s security and ignition system. Modern vehicles often use key fobs instead of traditional metal keys.
### Common Types of Key Fobs
1. **Basic Remote Key Fob**
– Buttons: lock, unlock, trunk, panic
– Works with a metal key you insert into the ignition
– ✅ Usually the **cheapest** to replace and program
2. **Transponder Key**
– Looks like a regular key but has a chip inside
– The chip communicates with your car’s immobilizer
– Without proper programming, the car won’t start
3. **Remote Head Key**
– Combines a transponder key and remote buttons in one unit
– Common across many mid-range vehicles
4. **Smart Key / Proximity Fob / Push-to-Start Fob**
– No physical key required to start (push-button start)
– Allows keyless entry, trunk access, sometimes remote start
– 🔒 Uses advanced encryption and rolling codes
– 💰 Typically the **most expensive** to replace and program
