For the last several years Southco has recommended Clancey Hardware and Hinge Co. in Overland Park Ks.
for replacement locks and keys for my Regal SE.
As of this date Clancey would not deal with me because I am not a volume buyer and not a certified company. They recommended I contact ECP Hardware Co. in the suburbs of Detroit Michigan. 1-800-442-3274.
I spoke to Claudia who took my order and shipped it today.I would recommend you to keep name and phone number handy should you need any supplies.
