I purchased a '09 Murano for my daughter, it is the first smart key purchase. The slot for the FOB is loose, not holding the key in secure. The spring mechanism is broken. We tried to have additional key FOBs programmed, as we only received one. Because of the loose port, it will not recognize its holding a FOB to release the code, to program new FOBs. Has anyone ever replaced the FOB controller card slot? After researching the cost of a new slot, from Nissan it's ~$500 for the slot itself. I do however, see them on Ebay less expensive. Any advice on doing the replacement myself?
