Thank you for your post! I do not believe that there is typically a delay between the time that the PIN is changed and its use in the PayPal system, but if you are experiencing a delay, it may be that the change hasn't fully propagated yet. If the new PIN doesn't work after an hour, please contact customer service for troubleshooting.
To contact customer service, please click Contact at the bottom of the PayPal website for available options, or reach out by Facebookor Twitter.
I hope this is resolved quickly!
