deleteKey on Keypad Touch returns success but password is not removed

[a16036868481]

Analysis

When calling the deleteKey command on a Keypad Touch device via Open API v1.1, the API always returns:

{"statusCode":100,"body":{},"message":"success"}
but the corresponding passcode is not actually deleted
It remains visible in the SwitchBot mobile app.
It can still be used on the keypad to unlock the door.
A subsequent /v1.1/devices call still returns the same key (same id, name).
In contrast, the createKey command works as expected for the same Keypad Touch device.

### Expected Behavior

I expect the `deleteKey` API for Keypad Touch to work normally. If it is supported, I would like to know what the correct JSON format for the request should be so that the passcode is actually deleted.


### Steps To Reproduce

1. Set up the following devices:
   - SwitchBot Smart Lock Pro (WoLockPro)
   - SwitchBot Keypad Touch
   - SwitchBot Hub Mini 2
   - Pair the Keypad Touch with the Lock Pro and enable Cloud Service.

2. Create a **timeLimit** passcode on the Keypad Touch:
   - Either from the SwitchBot mobile app, or using the Open API `createKey` command.
   - Confirm that:
     - The passcode is listed in `/v1.1/devices` under the Keypad Touch `keyList`.
     - The passcode is visible and usable on the keypad.

3. Call the `deleteKey` command on the Keypad Touch device:
```http
   POST https://api.switch-bot.com/v1.1/devices/{keypadDeviceId}/commands
   Content-Type: application/json
   Authorization: <token>
   sign: <sign>
   t: <timestamp>
   nonce: <nonce>

with body:
{
  "commandType": "command",
  "command": "deleteKey",
  "parameter": {
    "id": 12
  }
4.Observe API response:
{"statusCode":100,"body":{},"message":"success"}

5.Call /v1.1/devices again and check the same Keypad Touch entry:
The passcode with id: 12 is still present in keyList and status remains "normal".

6.Open the SwitchBot mobile app:
The passcode is still visible and can still be used to unlock the door.

### Logs

```markdown
[SwitchBot] deleteKey JSON body = {"commandType":"command","parameter":{"id":12},"command":"deleteKey"}
[SwitchBot] deleteKey response = {"statusCode":100,"body":{},"message":"success"}
[SwitchBot] createRoomTempKey result = {"statusCode":100,"body":{},"message":"success"}

Configuration

I am not using the official SDK or a config.json file.

I call the HTTPS API directly from a Java Spring Boot application.
My only configuration is:

switchbot.api.base-url = https://api.switch-bot.com

Environment

• Device: SwitchBot Smart Lock Pro + Keypad Touch + Hub Mini 2
• Region: Japan
• Open API: v1.1
• Integration: custom Java (Spring Boot) client calling https://api.switchbot.com/v1.1/devices/{deviceId}/commands
