Alarm and locking problems on Mercedes C-Class

Hello everyone, I own a 1999 Mercedes C-Class with a gasoline engine and 250,000 km. I am experiencing malfunctions with the alarm system and locking/unlocking problems. My alarm is stuck, the immobilizer is activated, and the steering wheel is impossible to unlock. Do you have any idea what could be causing these problems? Thank you in advance for your help.

Check the car's battery voltage first, as a weak battery can cause electronic malfunctions. Ensure the battery terminals are clean and secure. Let me know if this resolves the issue or if you need further assistance.
