Tedee smart lock Semi-locked and Jammed: uncalibrated
Risk level
Medium
Proceed carefully and stop if the check is unclear.
Urgency
Medium
Quick answer
For Tedee GO or GO2 using Matter, Semi-locked and Jammed mean the lock needs calibration. Check whether it remains paired with a Tedee account, because that decides whether to use the Tedee app or the physical Matter procedure.
Safety first
Stop and check this first
- If Jammed leaves you locked out, do not force the lock or treat calibration as an entry method: seek professional assistance through official Tedee support or a locksmith.
Safe checks you can perform
- Identify the GO or GO2 status and its Tedee pairing
- Start calibration using the identified official route
- Establish travel endpoints and inspect the resulting state
Leave these tasks to a qualified professional
- Do not attempt this professional task: Check which calibration route the Matter installation supports
- Do not attempt this professional task: Verify the bolt references used during calibration

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Check which calibration route the Matter installation supports
What they doThe professional establishes whether GO or GO2 is paired with Tedee and performs calibration in that app or through the Matter procedure applicable to the installation.
They must show youyour GO or GO2 account-pairing state and calibration starting in the appropriate interface.

Verify the bolt references used during calibration
What they doWith the door open, the technician checks that confirmed positions match fully extended and fully retracted bolts, without extending rotation beyond those reference points.
They must show youthe confirmed bolt positions and the state reported by Matter after completion.

Follow these steps
Note: Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.
Identify the GO or GO2 status and its Tedee pairing
- Who:
- you, using authorized access to the application controlling your Tedee GO or GO2.
- How:
- record whether the Matter platform displays Semi-locked or Jammed, then establish whether the same lock is also paired with an account in the Tedee app.
- Result that matters:
- identify the official calibration route for this particular Matter installation.
- If the Tedee account pairing is retained:
- use calibration in its device settings, even when Matter also controls the door.
- If the lock uses Matter alone without Tedee account pairing:
- the guide permits starting calibration with the button.
- Evidence to keep:
- displayed status, GO or GO2 model and whether Tedee account pairing remains active.

Start calibration using the identified official route
- Who:
- you, beside your installed smart lock with the door already open.
- How:
- for a Tedee-paired lock, open Calibration in device settings; for Matter-only operation, press the button five times within five seconds, keeping each press and each interval shorter than half a second.
- Result that matters:
- start the rotation-reference procedure without changing accounts or access permissions.
- If the app presents calibration:
- follow its instructions and confirm each step on the screen.
- If the Matter procedure begins with a blinking red LED:
- proceed to the manufacturer's locked-position reference.
- Evidence to keep:
- method used to start calibration and the first response from the lock or application.

Establish travel endpoints and inspect the resulting state
- Who:
- you or the attending professional, observing the bolts through the open door.
- How:
- fully extend the bolts and then fully retract them without adding spare rotation; confirm in the app or, for the Matter route, click once at each position with the LED first red and then green; when it blinks green quickly, finish with one click if your configuration does not use pull-spring, or two to calibrate it if it does.
- Result that matters:
- complete the locking and unlocking references required for smart lock operation.
- If Matter returns to Locked or Unlocked after calibration:
- keep that result alongside the original warning.
- If Semi-locked or Jammed remains:
- give Tedee support your observations for a calibration review.
- Evidence to keep:
- final Matter state and confirmation that travel stopped once the bolts were fully extended or hidden.

What it means
The official Tedee GO(2): Matter guide says Semi-locked and Jammed require calibration for the Matter-integrated GO and GO2 family. Tedee GO/PRO: calibration explains how to establish the bolt travel references. A Jammed device may still unlock once, but recalibration is required for continued operation. Different Tedee models or integrations can report other states; neither message alone proves that a motor or any other component has failed.
Warnings and stop conditions
- Highsource verified
If Jammed leaves you locked out, do not force the lock or treat calibration as an entry method: seek professional assistance through official Tedee support or a locksmith.

Symptoms and causes
Probable causes · in order
- Rotation references not established during setupCommon
Tedee setup requires the locked and unlocked positions to be established, and the calibration guide also covers this procedure after resetting the device.

- Recalibration still required through the correct interfacePossible
A GO or GO2 used with both Matter and a Tedee account must be recalibrated in the Tedee app; button-based calibration is reserved for a lock without that pairing.
