Service arrangements

Mail-in or a Dallas appointment

For supported ECUs, you can ship your controller to Cedar from elsewhere in the US. Contact us first to confirm compatibility and removal and shipping arrangements.

TCUs can be housed inside the transmission, making removal and shipping impractical. Tell us about your vehicle before arranging any removal so we can confirm how the service can be carried out.

AutoTuner’s “Mail-In Unlock” label describes a specific processing method. Cedar’s ECU mail-in options also cover other supported unlock methods.
