I recently bought a 2010 RT from a friend that lost the keys. I have it running now after doing all the work myself. You do not have to replace the ignition switch and DESS module together to get it running. BRP no longer list them online. But going to dealer websites them list just the new DESS module. All you need to due is replace just the DESS module and order key blanks from BRP. Take the trailer lock barrel if you have it or take off the rear trunk latch assy to a locksmith to make a key that fits X270 is the key blank number and use these cut key to cut the factory keys and you will have a extra to open everything and turn on to unlock parking brake. Service Manual says the DESS will go into programming mode automatically and will program the new cut BRP keys. You need at least 2 keys programmed. You can also buy the Master key from you dealer to be able to program extra keys. Master key is only about $30.00. I did find I had fuel delivery issue after getting to turn the engine over. I have $450.00 in parts for DESS, Keys, Master key and Locksmith chargers not counting my labor.
