Is it ok if I leave my key in the ignition?

While I was waiting for the new switch to come in, I tried to lubricate the steering lock. I removed the key cylinder with the key and paper clip, then sprayed a generous amount of dry lubricant into the slots toward the lock mechanism. The dry lube was ceramic/teflon spray with a tube on the nozzles stuck down the slots. Sprayed it several times in each slot. I put the cylinder in and worked the key on off then in and out a few times, I removed the key out for the night. Next day was cold outside and when I tried it it worked smooth and easy. I heard a clunk each time the key was removed. The key never worked so smoothly since I owned it. I'll keep the switch handy in case it goes bad.
