⭐ The KEYDIY B35-4, sold by some distributors as the B35-3+1, is the full-pad version of the B35 head: Panic and Trunk sit side by side at the top, with Lock and Unlock stacked underneath. It is a fixed Toyota style remote head key with a B Series wired board, so there is no transponder on it and no blade in the box. A KEYDIY generator writes the frequency and all four button codes.

⚙️ Key features

Panic button included

Speaker-marked Panic at the top left, for remotes with an alarm button.

Four-button pad

Panic and Trunk in a row over the stacked Lock and Unlock keys.

Fixed head design

A Toyota style remote head key, not a flip key.

🛠️ Programming instructions

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

The B35-4 carries no remote data until a KEYDIY generator writes it; the car then learns it like the remote it replaces.

Pick the profile: in the KD app or on the device, choose the car or the original remote and check that it calls for the 3+1 Toyota style head with Panic.
Generate: fit your own CR2032, connect the B35-4 and write the frequency and all four button codes.
Chip: where the immobiliser needs one, provide the original transponder or a KEYDIY Super Chip generated for the car.
Learn to the car: run the car's remote learn procedure or use your diagnostic tool; learn a new chip with your immobiliser tool.
Blade: not supplied with the head; handle the mechanical key as a separate part of the job.
Check coverage first: support depends on the tool's software version and the exact model year. Look the car up in the current KD app database first: the B35-4 only replaces remotes the app lists for it.

Frequently Asked Questions

Common questions about this product

Because the fourth button is a Panic button rather than a regular function. The pad carries Lock, Unlock and Trunk plus Panic, the layout North American remote head keys often use. Both names refer to the same KEYDIY B Series head.
Panic with a speaker icon at the top left, Trunk at the top right, and below them two wide buttons stacked for Lock and Unlock. A small indicator light sits near the bottom of the face, as on the other B35 heads.
KD-X2, KD-MAX, KD900, KD900+, KD-Mini and KD-X4. Pick the car or the original remote on the device or in the KD app, check the profile shows the 3+1 Toyota style head, then connect the B35-4 and write all four codes.
No. It is a B Series wired remote without a transponder. Cars that need a chip to start take the original transponder or a KEYDIY Super Chip generated for them, learned with your immobiliser tool. The remote side is learned separately afterwards.
No. The B35-4 is sold as the remote head only, without a TOY43 or any other blade. Treat the mechanical key as a separate part of the job and agree it with the customer before generating and learning the remote.
No. It is a fixed remote head key with no folding mechanism and no blade release button. Choose it for originals with a one-piece head that carries a Panic button; for keys that fold open, use a KEYDIY flip remote instead.
The band of the remote it replaces: the generator writes 315 MHz for most North American profiles or 433 MHz for most others, within a range of roughly 300 to 500 MHz. Nothing is fixed on the board before generation takes place.
Use the B35-3, which keeps Lock, Unlock and Trunk on the same Toyota style head, or the B35-2 for Lock and Unlock only. Matching the button count avoids a dead Panic button the customer would never be able to use.
