Two Saundersfoot men appeared before a crown court judge last week to admit a joint charge of burglary.
Lawrence Goldsworthy, aged 19, of Incline Way, entered his plea via a video link between Swansea prison and the city's crown court.
Jamie Thomas, also 19, of Sandyhill Park, appeared in person.
Judge Keith Thomas told them they would be sentenced after the trial of Simon Williams, aged 26, of the Caravan, Bramble Hill Farm, Ferry Lane, Pembroke Dock, who denies the charge.
Williams's trial will start on June 29.
Goldsworthy was further remanded in custody, while Thomas and Williams were granted bail.
Judge Thomas warned Goldsworthy and Thomas that prison sentences were the likely outcome.
