Im gettin a 99 srx 700, and it doesnt have a key. If its like a polaris or arctic cat, i shoul dbe able to just pull the plug on the ignition and it should start and run. Are the SRX's like that 2?
my 98 could be moved with the key switch unpluged but he warmers didnt work as i remember.
when it is out you can pry the back off and remove the tumbler so you can use a screw driver to turn it on and use the warmers.
i have a key switch with key for 28$ shipped to you priority mail
take the switch to a good locksmith - they can make you a key. We had to do that as we restored a "wrecked" sled, and it didn't have a key. Dropped the switch of at a locksmith, the next day had a set of keys for it.
