Ford Puma Remote Ignition Key Queries

After nearly 8 years I think the batteries may have finally gone in my ignition key so I'm locking using the key in the lock. The car still starts OK - should it do this with the key batteries exhausted or will it suddenly not start?

The handbook doesn't seem clear on actually removing the key cover to change the batteries. Does the cover just prize up with (for instance) the tip of a penknife inserted in the two oblong corner slots? It feels tight and I don't want to break any lugs off.

When new batteries are fitted will I have to go through all that re-programming procedure described in the handbook?

Finally, what is the spec. of the two batteries used?

Many thanks for any responses.

Er hello, it's me again - I think I've actually discovered the answer to one of my questions. Apparently the transponder in the key does not require a power source - it responds to an electrical field emitted by a transceiver located near the ignition switch, so the car should always start - right?
