1. Double-check that you’ve entered the security code correctly. Security codes are case-sensitive, so make sure that you’re entering it exactly as it appears.
2. Make sure that you have a stable internet connection. Sometimes, connectivity issues can prevent the account creation process from completing.

A:Engineer’s suggestion:
1.Update U rmware, calibrate machine, and try again
2.If not solve, go to perform Electrical Conductivity Measurement
Device information>> Electrical conductivity measurement>> follow the on-screen instruction below to test
Use a blank key or any other conductor to connect the probe and clamp/cutter and clamp in sequence to measure
3.If it shows “error 80, device calibration error can’t do universal key duplication”, maybe the dolphin key cutting machine is short-circuited,check if wires are broken or loose.
4.If all methods above still cannot U x the error, it needs to replace the main PCB
Provide your device SN to your dealer, if it’s under the warranty, and you can apply a new PCB free
