Abstract
Disclosed are shifting tools for opening and closing shifting sleeves. A disclosed completion system includes a completion string having a shifting sleeve movably arranged therein, a service tool configured to be arranged at least partially within the completion string and including a shifting tool having one or more shifting keys configured to mate with the shifting profile. When the shifting keys locate and mate with the shifting profile, an axial load applied on the service tool axially moves the shifting sleeve. If the shifting key is misaligned with a complementary shape of the shifting sleeve, a lower detent housing retracts toward an upper detent housing against a force of a detent spring to allow the shifting keys to retract while maintaining a radially outward force. If an axial load is removed, the housings are automatically retracted by a return spring, causing the shifting keys to disengage.
