This is a rare occurrence, but can happen if you get out of the starpilot program and start using the TI for various math functions and memory operations. Normally just quitting and using Green diamond + 1 will get you back to starpilot, but if you have completely locked up keys for some reason, here is what you can do.

You will need to reset your calculator. This is done by removing one of the alkaline batteries from the unit and while holding the [(-)] key simultaneously with the [)] key and pushing the battery back into the unit. The procedure is described in the TI manual. Note that after you push the battery back into the unit you will need to continue to hold both the [(-)] and [)] keys down until the unit resets itself and comes back to life.

The above procedure erases both the RAM and ROM memory in the calculator and sets the unit back to its factory defaults.

You will need to reload the StarPilot program after the reset. To do this you will require a TI-Connectivity kit. You can purchase one at Walmart or other local TI reseller. We have the kits in stock if you would like to order one from us.

After you receive the cable we recommend you upgrade the TI operating software.

If you have a very old calculator.
Older versions of the calculator OS had problems when removing the batteries as you have discovered. The latest version (as of December 2018) of the OS is TI AMS 3.10 (came out in 2005), but you can use anything 2.09 or newer. Anything older will need to be updated. Upgrading the OS is very simple if you run the TI-Connect software that comes with the connectivity kit while your computer is hooked up to the Internet. The software will detect the update and download and install it to your calculator. Follow the the instructions outlined by the software. If you have 2.09 or newer, you do not need to update. The new OS will not improve the function of the StarPilot.

Download and install the StarPilot software once the TIOS upgrade has completed. You will need your KEY to activate the software. The key should be glued to the lid of your unit. The StarPilot software is on a CD that was shipped with the calculator. You might consider upgrading your StarPilot software to the latest version. The latest StarPilot software can be downloaded from our website at www.starpath.com in the downloads section.

You can also ship the unit to us for the upgrade if you prefer. There is $25 service fee + shipping to upgrade your unit. You can ship the unit to

Starpath
3050 NW 63rd St
Seattle, WA 98107

Please include your shipping address and credit card billing information with the unit. You must still have the KEY for your calculator to make any of these system adjustments or to update the software. That KEY is usually taped to the inside of the plastic cover of the unit.

Note from user Herman Dekker. Thank you Herman.

I.
For the last time this year I have one addition for Starpilot installed on the
TI-89 Titanium that can be useful for everyone when the Calculator Stalls.

You have written about this on 23-09-2004 and 23-11-2007 on the TechSupport.
If the calculator has locked up and does not respond on any key
or the F5 F5 calc function does not longer work, cleaning the memory is
the only option. If it is locked, remove the batterys and the backup battery.
But then you have to reconnected to a computer to reload the program in the ROM memory and then reinstall it.

If no key responds there is (on the TI-89 titanium) one other option to clear the
RAM memory. You have to push 4 keys simultaneously.
With right hand push [2ND] [←] [→] with left hand push [ON] release then all keys.
The screen shows "Installation in progress" Do not interrupt.
The RAM memory is now cleaned but ROM not.
You can now reinstall Starpilot with 2ND VarLink and SPsetup() enter the key
and you are back in business.
Especially on board where is not always one computer available this is a much
safer method to proceed by a locked TI-89.
