According to the manual starting on page 52, you need to de-register all handsets then re-register the handsets one at a time. The manual covers both cordless model numbers so the handsets should be interchangeable. I have included a link where you can download the manual if you need it.

First, you need to de-register the handset from the current base. Then register it to the new base. On the handset, press Menu then navigate (up/down arrows) to Handset Settings and press OK. Next navigate to Registration and press OK.

For deregistration: navigate to Deregister then press 3 3 5 . Then select which handset to deregister (1-6) (the handset number will flash when it is selected) and press OK. Select Yes and then OK. When the deregistration is complete, press OFF.

For registrations, navigate to HS Registration then press OK. Then move to the base and press and hold the Locator button until the registration tone starts. If all the handset ring, press the locator button to stop the response and start over. Within a minute and a half of the registration tone starting, press OK on the handset and wait until a beep sounds and the symbol on the screen stops flashing.

The user's manual is available here: http://www2.panasonic.com/consumer-electronics/support/Phones-Fax/Telephones/Expandable-Systems/Operating-Instructions/model.KX-TG1033S.O#ts . It's in the tab marked Operating Instructions. This will provide additional setting information.

I hope this helps.

I believe you have the expansion capacity of the phone all used up. The phone cannot register any more handsets until you delete the handset registered that is not in use. First check the handsets and see what handset numbers they carry. It should be #1,#2,#3,and #4 if it does not then you will have to delete the one that is missing or if it is then delete handset #5.To do this you will have to use one of the handsets registered to the base. First Press the MENU/ OK button then scroll down to ADV,SETTING then Press MENU/OK then scroll down to DEREGISTER then Press MENU/OK. Then ENTER HANDSET PIN would show, if you have not changed the pin enter 0000 if you have enter your pin member. From the next options select HANDSET and press MENU/OK from the next set of options select the handset number you want to DEREGISTER and press MENU/OK from the next option select YES then MENU/OK. Then try to reregister the new handset To do this Press the MENU/OK button then go to ADVANCE SETTING press MENU.OK scroll to REGISTER then press MENU/OK Select the base number displayed then press MENU/OK. PLEASE WAIT will appear. Then from the base press and hold the PAGE button until the handset prompts you to ENTER PIN # .Enter 0000 OR your pin number then you will see PLEASE WAIT.
