Mercury Repair Questions? Ask a Mechanic for Answers ASAP
Hello, Eddie here and I will do my best to help. Did you check the plug at the transmission neutral safety switch? make sure it's plugged in, if it is, try it in park, or better yet, hold it in start and pull the gear stick through the range, Let me know what happens there.
Alright, when you turn the key to the ON position, does the security light go out? or does it stay lit or blink on the instrument cluster?
OK, With the key ON, it should go out, if it continues to flash, that is a problem. Unhook the battery neg. cable, and wait 5 minutes, reinstall the negative bat. cable, and close all the doors and trunk and hood. Then put the key in the drivers door and lock and unlock the drivers door a times. Let me know if that helps.
Alright, do you have a scanner by chance? code reader? if so, have you checked codes in it? to see if it was setting anything?
I gotcha, a spare key? is there a spare key somewhere?
I follow you, Only thing I can suggest at this point, is maybe borrowing a scanner from a local auto parts store. They usually have one they loan out for a deposit that you get back when you bring it back. But it really needs to check codes in the PATS system. I definitely believe it is security related though as the light blinks the whole time the key is on. A mobile locksmith can come out and program and cut you another key for not too much. That may fix it. Hard for me to say exactly what would be wrong without fault tracing it with a scanner however. If you call a mobile locksmith, they will come out to you, and likely tell you what is wrong with it as they have the equipment to scan for codes and program keys. That's probably what I would do if it was mine. Let me know if you have any further questions. Thank you.
