How to fix a stuck key in my Vauxhall Zafira Life?

One of the keys in my Vauxhall Zafira Life is stuck and won't turn, making it impossible to start the car. What could be causing this issue and what steps can I take to fix it?

First, check if there is any debris or dirt blocking the key or the ignition switch. If so, carefully clean it out with a soft cloth or compressed air. If that doesn't work, the key may be worn out and in need of replacement.

Another possibility is that the key has been bent or damaged. In this case, you will need to have a replacement key made by a professional. Be sure to use a dealer or certified locksmith to ensure a proper fit and programming.

If the key is not the problem, it could be an issue with the ignition switch itself. This can be a complex and delicate repair, so it's best to take your car to a mechanic for professional assistance.
