The problem of AK500 key programmer write key the remote doesn’t work

AK500+ Problem: after use AK500+ key programmer to see out MCU data in the EIS, I input EIS data into SKC calculator to alternate key data, and write the true secret data into key. I then can begin in the vehicle, no handheld remote control.

Problem Reason: you erased remote byte inside the NEC chip on the key. Usually, the chips number have 40229 or 071 are often erased.

Solution:

1. Try and plug and write more than once, sometimes the repeat operation could make the remote work again.

2.For hc705, the MCU enter in the EIS doesn’t display VIN and odometer.
