I am going to bet this is a software problem!
Just some of my research on this:
Prior to 2014 the Spyder used a fixed code DESS key system. That is each key has a unique ID programmed into it that cannot be changed. The chip used in these keys is a T5 chip and each chip comes with a unique ID from the chip maker. You add a keys ID to the Spyder using a master key and you can add up to 4. These keys can be cloned. What is interesting here is BRP was behind in the technology using the T5 chip. Most car makers abandon fixed chip keys in about 2006. Spyder came out in 2008... So BRP was using pretty old technology at launch of the Spyder.
Since then two other technologies came out.
Rolling code:
In basic principle - The car actually writes to the key the next code mathematically calculated by the car. This equation is different for each car. Thus the car wont start unless the key and the car matches the same code. Every time the car is started, it rolls the code and writes it to the key. The idea is to keep you from cloning the key since the clone will have the last code in it so if you use your original key the clone wont work the next time. But some have found ways to clone these keys now.
Crypto code:
The car has a encryption code (a formula) in it. Every car has a unique formula. They keys are programmed with the same encryption formula. When the key is read by the car, the encryption formula must match and then the ID of the key is decoded and provided to the car. In other words, you cannot read the ID of the key without it being decrypted using the cars unique encryption formula. Also the key is not written to by the car each time like with the rolling code so the key never changes. Because of the encryption, the ID of the key cannot be read by a key cloning device since it doesn't know the encryption to read the ID. (actually I have read some have cracked this so they can be cloned today).
Obviously BRP is using one of these technologies in the 2014 and up.
Based on this issue I am betting is it the rolling code and I bet this is a software issue not hardware.
What I think is happening is either there maybe a software glitch and the key is not getting reprogrammed it's new rolling code, or if it is, they system is not correctly keeping the new code. Thus the key and the system now have a different code. I bet there is something in the software to resolve when this happens that maybe has a time out on attempts to get the code to match. This is buggy and after a few code not matched errors, it locks you out. This is why I think some get past the DESS error and some get stuck to see a dealer.
Now I am not saying all the DESS problems are a software bug. I am sure some were hardware. But I bet a lot of the problems is a bug causing a key to no longer match the Spyder.
Time will tell but this is my theory.
