Bought a car with a faulty key

[AvidScotsman]

Hey guys, looking for a bit of advice. I bought a Jaguar XF 2014 at the end of Nov 21. The car drove fine and all seemed in order until I got to handover. I got handed 2 keys for the vehicle which one of them didnt seem to work (remote fob). The salesman said to me probably needs a new battery in it so I thought fair enough, do that when I get home.

So I replaced the battery and all was okay, or so I thought. Next day it's dead, replaced it again and the same happened. I suspected there was a fault on the key draining the battery. Anyway I get in contact with the garage who say to send it across to have it repaired.

Long story short, 6+ weeks later, they say the battery is running flat after 4 days, we can't get it to run any longer. "So I take it you will be replacing the key then?" No. They are refusing to replace the key despite selling the car to me with 2 working keys. I'm under the impression that the car was sold with 2 working keys and they have sold me a faulty key with the car. Now they are refusing at all costs to replace it.

Does anyone have any advice on the matter?

My point is it was advertised as a car with 2 keys. I didn’t know it wasn’t working until I was about to drive away. One key didn’t work, which to me seemed like the salesman didn’t know about it either. I had my wife and baby with me so I was kind of worrying about getting home. There was no precursor warning that a key wasnt working at any point. Just because one key is working doesn’t make it okay to have one that’s sold not working. Keys these days can be upwards of 200 pounds and now when I sell the car I will have to stipulate that it has a second non working key.
