Simple RFID (EM-Marin (yes, like that)) and wired (Dallas, Cyfral, Metacom) key duplicator with arduino. Supports EM4305, T5577, RW-1990.1 RW-1990.2 TM-01 TM2004 protocols. There are connection schemes in the project. Baud rate: 115200.
A device (key) support list is given below.
| KEY | DALLAS | CYFRAL | METAKOM |
|---|---|---|---|
| RW1990 | RW | - | - |
| TM08 | RW | - | - |
| KC-4TM | RW | - | - |
| TM01 | RW | R W* | R W* |
| RW2017 | - | R | R |
| RW15 | - | R** | R |
| KC-07 | - | X | X |
Do NOT attempt to program your TM01 keys with this yet!!! You WILL break them; this function is NOT yet properly added!
KC-07 does not read likely due to it using high voltage. RW15 requires this config: load resistor ON; speed is lower than "Very fast". RF chart below
| KEY | SUPPORT |
|---|---|
| ATA55XX | RW; EM-marin only; unlocked only |
| EM4305 | Unknown |
| H5 | X |
| H7 | X |
| iKEY OTP | X |
Better translations! Ain't that what-cha want? Manual code adding too. HOMEMADE UNIVERSAL KEYS!!! LET'S GO!!! I'm finding out whether A1 TM emulation works.
Tap the key to the TM/RFID reader, whatever is appropriate for your key.
Hold down the encoder button (D8 to GND). A confirmation signal will be given.
Click the encoder button until the RED (D2) LED is on. Tap the target key to the appropriate reader and wait for confirmation. If it fails, try again.
Click the encoder button until the BLUE LED (D4) is on. Then, approach your copier to the reader.
Scroll the encoder.
Tap the original key to the reader. Then, hold the encoder button to save. Wait for a confirmation tone.
Send e in serial monitor.
DANGER! If you do not wait for the OLED screen to reset, you risk bricking the Arduino.
okay, quick edit - I think that was just a bug of my chinese arduino bootloader, so, just so you know. it never happened again.
Send t in serial monitor.
This needs a PC! For now.
Open the serial monitor and tap your tag to the reader. You will see data: ID XXX key YYYYYYYYYY. Convert these values to hex. The data is the code.
Example: VIZIT universal: 56:5A:11:40:BE = 86 + 1511080126
