I don't use any passkey. Access points work differently than other BT devices and you don't actually need to pair with one. But you can if you like.
To connect to the access point, go to Prefs and select connections. Create a new connection and name it whatever you like. Connect to: Local Network. Via: Bluetooth. Then tap on the device box to find and select your access point.
Next, go to prefs, Network. Select the new connection you created for "Service:". Leave username and password blank. Tap the Connect button. Now launch WebPro and you should be able to surf the web!
