It won't open the car anymore and I'm having to use the key in the door , any idea what's wrong??

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Changing out the battery did not work to make it function again.
Can anyone help, my battery went flat on my key, everything was fine before, I've put a new battery in which is the right one but now my key doesn't have the rapid flash you usually get and now Just does a single flash on the key , if you hold the button down it flashes like once a second . It won't open the car anymore and I'm having to use the key in the door , any idea what's wrong??
Have you tried opening the door, putting key in ignition, starting the engine, shutting it down, exit the car and see if it works then? Is the battery inserted the right way? I have also heard that reversing the battery for a couple of seconds, then putting it in the correct way sometimes works.
You could just try another battery, sometimes you just get a bad one from the factory. A short flash suggests the voltage is holding up enough to start the transmission then dropping quickly as current is drawn. I've had a number of supposedly "fresh" batteries not work and give similar behaviour to what you describe.
If you have a multimeter, take the battery out and measure the voltage between the top and bottom, if it's below about 2.7V then replace.
I find these batteries only last a few months in my key, they seem to go flat very quickly, not that this is the problem you have.

Just as a point of reference - my key gave up the ghost many years ago. Was always a bit flaky from the beginning. The circuit board in the key stopped working, probably because of old solder connections on the circuit board. Changing out the battery did not work to make it function again. I can put in a new battery and it does just like what you said, it blinks or stays solid but does not unlock/lock the car anymore. Maybe replacing the battery caused the circuit board to finally fail. No amount of voodoo steps to try and get the key to "talk" to the car again ever worked. Been using the manual key ever since. I have no problem with that. It's been like over seven years doing that.
