For the smoothest experience without a numpad, I strongly recommend editing trainer.ini as described in method #1. It takes five minutes, requires no extra software, and once set up, you never have to think about the numpad again. If you frequently switch between multiple games or use other mods, AutoHotkey is a great universal fallback. But avoid trainers that force numpad use without any configuration—they’re simply outdated.

If you don’t want to change any software settings, you can buy a cheap USB numeric keypad (often $10–15 on Amazon). Plug it into your PC, place it to the left of your main keyboard or anywhere convenient, and use it exclusively for the trainer. Alternatively, use Windows’ built-in On-Screen Keyboard ( osk.exe ), click the “Options” button, and enable the numeric keypad. Then you can click the numpad keys with your mouse while playing. This is clunky but works in a pinch. gta 4 trainer no numpad
Most gaming laptops have a numpad embedded into the main keyboard, usually activated by holding Fn (Function) and pressing certain keys (e.g., Fn + U = Numpad 8, Fn + J = Numpad 2, Fn + K = Numpad 6, Fn + H = Numpad 4, Fn + I = Numpad 5, Fn + M = Numpad 0). Check your laptop’s user manual. If this works, you don’t need any modifications—just hold Fn while pressing the corresponding letter keys. Unfortunately, this is awkward for fast-paced trainer use, but it's an option.
Another trainer option that avoids numpad dependency is or the newer ZMenu . These trainers often use a different control scheme by default—sometimes arrow keys or even a mouse-driven interface. ZMenu, in particular, is designed for modern usability and allows you to click on menu options with your mouse, completely eliminating the need for a numpad. However, note that ZMenu may require Script Hook V .NET and might not have as many features as Simple Native Trainer. If you only need basic cheats like god mode, infinite ammo, car spawns, and teleports, ZMenu is a great no-numpad solution. For the smoothest experience without a numpad, I

Save this as gta4_numpad.ahk , install AutoHotkey, double-click the script, and then launch GTA 4. Now, your letter keys will act exactly like the numpad inside the trainer. The trainer never knows the difference. You can also use keys like ] , [ , ; , ' , , , . , / if you prefer. But avoid trainers that force numpad use without
