How do I get my Zafira 2017 plate to start after Anti theft deterrent system has come onto display on dashboard. I have no power to start the electronics as battery won’t start the ignition

In the first instance, I would contact a Vauxhall garage to offer some guidance.

After some googling, there are lots of possibilities, but they vary for different make/model. Here are a couple of suggestions;

• Try unlocking the door a few times with the mechanical key
• Put the key in the ignition and turn to 'On', leave it there for 10+ mins, turn back to 'Off' and repeat

Let us know what the solution was for your Zafira.

• With a fully charged battery, put the key in your Zafira’s ignition and turn it like you are going to start the engine. Leave the key in the on position. You’ll see the little padlock symbol, security light, or service theft deterrent system message.
• Once the padlock goes out (takes about ten minutes), try and start your Zafira.
• If you repeat this process three times, the key should start working, and the padlock symbol should disappear.

And if that doesn't work you can try these depending on what GM anti-theft system you have; Passkey or Passlock.
