## 🔍 What Is Key Fob Programming?
A **key fob** is the small remote or smart key you use to:
– Lock/unlock your doors
– Start your engine (with push-button start or proximity sensors)
– Open the trunk
– Trigger the alarm
**Programming a key fob** means syncing it with your vehicle’s onboard computer so the car recognizes it as an authorized key. This process often requires:
– Access to the vehicle’s **Onboard Diagnostics port (OBD-II)**
– Specialized **programming tools/software**
– Sometimes **security codes or PINs** from the manufacturer
Without proper programming, the fob may unlock the doors (in simple systems) but **won’t start the engine**, especially in vehicles with transponder chips or push-button ignition.
