Also if manual put it in 1st drivers seat belt on and hazards

Optional Solution:

Try leaving the ignition on even when it asks you to turn it off, or disconnect the battery for a while and try again.

SID87 EVO if password protected can be done obd, if non password protected boot only,, should still connect to update to latest software.

User feedback:
Disconnected battery for some time did the fix and worked

How to Choose Keydiy KD VAG MQB49 5C 5D Keys ?

How to Choose Keydiy KD VAG MQB49 5C 5D Keys ?

One of the biggest challenges whe working with VAG MQB49 vehicles is identifying the exact remote type-whether it’s a flip key, a smart key, an older model, or a newer generation. Getting it wrong can waste time and create unnecessary complications.

With KeyDIY (KD) devices, however that distinction is no longer necessary when programming 5C and 5D keys.

Key Advantage: No Manual Pre-Generation

Unlike many other programming devices, KD equipment does not require the technician to pre-select or pre-generate a program before reading the key. During both the key reading process and dealer key generation, the KD device automatically matches the appropriate program in the background. This seamless process means the technician can focus on the job without having to manually indentify the remote type.

Supported 5C Types (including all ZB remotes)

The KD platform fully supports the following 5C remote types:

Regular ZB15-3 is not an OEM solution. DZ-ZB15-3 and DZ ZB15-4 are OEM solution remote.

Supported 5D Types (specified FGB remotes)

For 5D keys, KD supports the following FGB remote models:

Bottom Line
Whether you are dealing with an older 5C remote or a newer 5D FGB model, the KD device eliminates guesswork. Automatic program matching simplifies the workflow, reduces errors, and saves valuable time on each job.
