Unacceptable Immobilizer Failure

I am the 84-yr old owner of a 2019 Thruxton R with only about 1000 miles on it which I am unable to start due to an immobilizer fault. Just before the start of COVID I made the mistake of stopping the bike with the kill switch and leaving the key in the ignition resulting in a dead flat battery. More recently, in anticipation of being able to ride again, I purchased a Shorai battery and installed it only to find that the alarm light remained on continuously when the ignition key was turned on, indicating an immobilizer fault.

I now find that to correct this failure I must rent a truck and transport the bike to a dealer who will then restore the registration of my key to my bike's immobilizer unit. In addition to the cost and inconvenience of transporting the bike, I will be charged for at least an hour and a half of labor.

I am beyond angry that despite having proper keys for my bike, allowing my battery to discharge could cost me hundreds of dollars and this amount of aggravation.

Does anyone know how to deactivate the immobilizer? I have purchased a 2nd immobilizer on ebay but the connector on the unit does not seem to match any of the pictures showing bypass connectors. I do not want or need any alarm functionality on my motorcycle.

Had I known that I would be unable to start my motorcycle with its properly matched key because of a battery voltage drop I would never have purchased it. I consider this failure mode to be nothing less than unacceptable design flaw. If I am faced with trucking this motorcycle I will probably just put it up for sale to someone who is able to transport it.

 

Thanks. I suspect it would more likely be a large capacitor which would hold a charge long enough to allow for the bike's battery to be replaced since the immobilizer is a sealed unit. However no storage component would do the owner any good under these circumstances because the key matching would presumably be lost when the immobilizer became discharged unless the matching code was held in eeprom.
I did purchase one to get the connector for patch wiring but I've discovered that a new Triumph dealership has opened quite near to me so finally decided to just have my unit reprogrammed. Then I will be able to sell the bike without an unsupported modification. At this point I have pretty much lost confidence that that I won't be faced with this issue again.
I really find it hard to excuse a design that prevents the owner from starting the bike using his key alone after making repairs given the likelihood that a thief would simply load the bike into a van and drive away if faced with the issue.
