Hello

I have a 2009 vauxhall corsa 1.3, I recently changed the battery as my other one was flat and when given a jump it wouldn't start. I then took my car for mot after replacing battery and it failed due to anti roll bar which they replaced and then i drove my car home fine. Next day i went to use it I turned the key and it wouldn't start it wouldn't turnover, after a couple of turns it worked. I drove it for 5 minutes and it cut out on me and hasn't started at all, when i turn the key it doesn't make any sounds just the lights on the dash come on and radio. I've been told it could be the immobiliser.

Any thoughts on what the problem could be or advice?
