Fix:

Delete (or rename) keys.dat, then launch the game. Vice City will generate a fresh default version automatically.

Modding `keys.dat`: Adding Support for Modern Controllers

Modders have reverse-engineered the keys.dat format. It contains a series of device descriptors followed by arrays of button-to-action mappings. To add support for a new controller (e.g., DualShock 4): gta vice city keys.dat

Identify your controller's VID and PID: Use a tool like USBDeview or check Windows Device Manager → Properties → Hardware IDs. You’ll see something like VID_054C&PID_09CC (Sony).
Open keys.dat in a hex editor and locate the "JOYSTICK" section.
Insert a new device block with your VID/PID and then copy the mappings from a known working controller (e.g., Logitech Dual Action).
Recalculate checksums – This is the hardest part. Without a proper checksum, the game will ignore your entry. Some community tools like VC Controller Configurator automate this.

Warning: A single misplaced byte will break the entire file. Always backup your original keys.dat before attempting to mod it.

📁 Where is it located?

Original CD/DVD version / Steam version (pre-Definitive Edition):
C:\Program Files\Rockstar Games\Grand Theft Auto Vice City\data\keys.dat
Definitive Edition (Remaster):
The remaster uses a different input system; keys.dat is not present in the same way. This post applies to the original PC release.

Purpose

The keys.dat file in GTA: Vice City is used by the game to track which keys (in-game pickups or unlockables) the player has obtained and to control access to certain locked doors, gated areas, or mission triggers. Modders sometimes create or edit a keys.dat to add custom locked areas, change which keys unlock what, or to replicate savegame behavior.

Q: Does `keys.dat` contain my saved game progress?

A: Absolutely not. Saves are in .b files (e.g., GTAVCsf1.b) inside the User Files folder. Do not confuse them.
