wheel lock key

I just recently purchased a 1987 Chrysler Lebaron from a used car dealership. I took my new vehicle into an auto shop the other day for an inspection and I was asked for a wheel lock key so the breaks could be inspected. I had no idea what this was and didn’t have one. The auto shop could not locate one within the car either. I have been all over town looking for this key and I have gone to several tire specialists, none of which were able to help me out. I’ve searched EBAY and Craig’s List, none of which had this key. I even went back to the used car dealership and they didn’t have it either. I am at the end of my rope and I have no idea what to do. I am a little concerned because if I get a flat tire or if my breaks go out, I won’t be doing so well. I was wondering if you have this key or if you could point me in the right direction?

LOL, the above message is what I was sending to dealerships and auto mechanics. I just copied and pasted. I'm not asking any of you if you have the key, but if any of you have any suggestions or ideas. Thanks :smokin:
