⭐ The KEYDIY B22-4, also listed as B22-3+1, is the GM style flip remote with the Panic button the 3-button B22-3 lacks: Lock and Unlock in a row, a round Trunk key, then a red Panic button at the foot of the chrome-framed pad. The B Series board is remote only, and the shell takes the car's transponder in a slot. A KEYDIY generator writes frequency and all four button codes.

⚙️ Key features

Panic at the bottom

A red Panic button under the round Trunk key, for remotes that carried an alarm function.

🛠️ Programming instructions

🔌GENERATE WITH A KEYDIY DEVICE, THEN ADD TO THE CAR

The B22-4 is blank on delivery: a KEYDIY generator writes the remote data, including the Panic code, then the car learns it like the original remote.

Find the profile: in the KD app or on the device, select the car or the original remote and check it asks for the 3+1 GM style shell.
Generate: fit a CR2032, connect the B22-4 and write the frequency and the four button codes.
Transponder: slide the original chip or a KEYDIY Super Chip generated for the car into the slot.
Learn to the car: use the car's remote learn procedure or your diagnostic tool; learn a new chip with your immobiliser tool.
Blade and test: fit and cut a KEYDIY-pattern flip blade, then test Lock, Unlock, Trunk and Panic on the car.
Check coverage first: support depends on the tool's software version and the exact model year. Check the car in the current KD app database first: the B22-4 only replaces remotes the app lists for it.

Frequently Asked Questions

Common questions about this product

The B22-4, also sold as B22-3+1, is a universal KEYDIY B Series flip remote in the GM style shell with four buttons: Lock, Unlock, a round Trunk key and a red Panic button. A KEYDIY generator writes its frequency and button codes.
Three main buttons, Lock, Unlock and Trunk, plus one Panic button set apart in red at the bottom of the pad. B22-4 and B22-3+1 are two names for this same remote; the B22-3 is the version without the Panic button.
KD-X2, KD-MAX, KD900, KD900+, KD-Mini and KD-X4. Look the car up on the device or in the KD app, check that the profile asks for the 3+1 GM style shell, then connect the B22-4 and run the generation to write all four buttons.
There is no chip on the board, but the shell has a slot that takes a small glass or carbon style transponder without opening the remote. Move the original chip into it, or fit a KEYDIY Super Chip generated for the car and learn it.
The frequency of the remote being replaced, written during generation. The board covers both 315 MHz and 433 MHz, so the same B22-4 serves North American remotes and the 433 MHz remotes used in the Gulf, Europe and elsewhere.
No. Fit a KEYDIY-pattern flip blade in the profile of the car's original key, HU100 on most GM flip keys, with a roll pin, then cut it to the original. The blade and the cutting are bought and done separately from this remote.
No. GM style describes the shell and its button layout. The B22-4 replaces any 3+1 remote the KD app lists for it, whatever the make, so check the target car in the current database before quoting, and match the Panic function to the original.
One CR2032 lithium cell, not included in the bag. Fit a fresh cell before generation so the board answers the device during the write, then test Lock, Unlock, Trunk and Panic on the car once the remote has been learned with its own procedure.
