Pop out ign. switch

[sphooch]

I just found a pop out switch, complete with cable , in as new condition , but the keys don't turn the lock. after a little cleaning up i found the made in spain logo on the back. does any one know about when this could have been made ?? and most importantly is there any way i can take it apart so as to maybe get a key made ? I'm sure someone has run into this problem thanks hooch
