Help please? 182 boot won't lock off fob

[cliodriver17]

Only just noticed today that the boot on my 182 doesn't lock off the key fob, had a look around the forum and lots of people have had the problem of the boot not opening but haven't found one for the boot not locking. Has anyone else had this problem and found a solution?

My first thoughts are that the solenoid is stuck open..

Any guidance would be greatly appreciated [emoji4]
