When the key is inserted into the ignition or brought inside the cabin of a push-to-start automobile, the car's induction coil sends out a burst of energy to the chip.

- Hardware Damage: Using cheap, unverified "cloned" keys from the internet can sometimes short-circuit the transponder coil in the guiding column.
Contrast Table: Professional vs. DIY
| Function | Specialist Service | Do it yourself Attempt |
|---|---|---|
| Success Rate | Near 100% | Variable (20-50%) |
| Equipment | Professional Diagnostic Tools | Generic OBD-II or None |
| Time Spent | 15-- 30 Minutes | Hours of Research/Trial |
