Both my ignition keys are now difficult to put into ignition slot. A little lubricant hasn't made any difference. I think both keys might be worn out as the second less used key is now playing up some 18 months after swapping over. Be grateful for any advice on what i should do.

You may be able to get some keys recut and just replace the blade inside the fob.

Having loads of keys and keyrings hanging from the ignition key is a good way to introduce wear into the mechanism due to undue weight hanging off the key
