[Corey Cohron RIP]

1. Depending on when you purchased your programmer, it might not have a sticker! If there's no sticker, follow Bill's instructions to retrieve it from the unit itself.
   
2. If you purchased your Gryphon directly from us, the serial number is usually your invoice number.
   
3. If you purchased your unit from one of our dealers, the serial number will be a six-digit number that's exclusive to that dealer.
