Walk Behind Lawn Mowers

I purchased a Husqvarna GT 48 XSLi from Jacks Small Engines online earlier this year, new and in the Husqvarna shipping crate.  Their Order 1215000, on 5-2-2017.  Model # 960430177-00, Serial Number 050516A 006280.  I believe the machine was built in 2015, based on the information on the crate.

 

I like the machine.  However, I now have 8 hours on it and the Smart Switch is keeping the engine from starting.
First of all, it has never accepted anything but the default code.  I have not been able to successfully load any other code. But at least I could use the machine.

 

My trouble now is much worse.  I have to use the machine and it won't let me.  I go through the Smart Switch start sequence and get a green light for a split second, then both the brake light and mower deck clutch light blink red, off and on.  The result is I can't turn the engine over or complete the start sequence.  All other safety shut-downs are in working order.  Seat, oil level, etc.  The brake is engaged and the mower deck clutch is disengaged.  This appears to be a fault in the smart switch itself.

I would like to receive another smart switch under warranty and I'll return this one.  How do I go about doing this?
Better still, I'd like to simply replace this smart switch with the equivalent manual switch.  It seems a lot of folks have trouble with the safety switch, according to many comments on Google.

My local dealer is not an option.  My nearest dealer is 30 miles away, Z Equipment, and they charged me $150.00 every time they picked up my old Husqvarna for service, and then took forever to get the work done, sometimes requiring two or three trips for the same basic repairs.  They did not have this machine available, anyway, which is one reason I bought it from Jacks. I like this combination of power and size and the locking differential.  I am fast coming to the conclusion that I don't like the smart switch.
