Hi looking for some help. 2016 W453 Gas the key is stuck in Ignition I can’t turn it passed half way to remove it. Everything works fine and no CEL. Car drives fine and recognizes P N R D so it’s not like it’s not in park and key won’t come out. I can’t even lock the car with 2nd key. I disconnected the battery to see if it resets and nothing. Any ideas?

Other brand vehicles, have what is called a immobilizer. When the battery gets low, or is dead. Your not able to remove the key from the ignition, or lock the doors. Safety feature. Check your owners manual, there might be a slot, to release the key from your ignition switch. Just guessing if smart offers that.

I think I found it, it’s a common issue. I’ll try and fix tomorrow, see this for others who have same issue Facebook Groups

I fixed it using the instructions on Facebook. The key lock Solenoid was stuck, it’s a easy fix.

remove steering wheel top and bottom covers there are 4 screws, 2 below and 2 in front have to turn steering wheel half way.

once cover is remove you can see the Key Lock Solenoid Which has 2 screws on it also. Remove solenoid, push in pin with thumb, install and check key functions and it’s fixed. Put back everything together

from what I read you can’t purchase the solenoid separate so it may get stuck Again. Some have removed the solenoid completely but this will cause the key to be removed in any gear or position.

you see that rubber plug on the opposite side of the pin.Remove it and clean any material that is causing the pin to stick once that it cleaned off your good. Seems like a poor design rubber cap melts and jams the pin.

This thread and the information included here help us immensely. We were traveling to our son’s in Colorado when the got stuck in the ignition and would not release. The information contained here is exactly what we needed. Thank you. Since the car is still under warranty we will be contacting smart/Mercedes.

(08/13/21) I realize the post is time stamped, I just thought it would be worth noting this helped me a year later. I followed the instructions, removed top and bottom, cleaned the pin, and it’s all good now! Thank you so much!!!

Remove top and bottom part of the plastic where the ignition is and remove the solenoid. Remove the melted rubber in the bottom, clean, lube top and bottom pin. Then put back together and test.
