1. A wellbore intervention system, comprising:
a first whipstock configured to run into a wellbore formed from a terranean surface to one or more subterranean formations, the first whipstock comprising:
a first bore of a first diameter that extends from an uphole, angled face of the first whipstock to a downhole face of the first whipstock, and
one or more first keys formed on a radial exterior surface of the first whipstock and configured to secure into one or more first keyholes formed in a casing that is secured in the wellbore to position the first whipstock adjacent a first lateral formed from a first lateral window in the casing;

a second whipstock configured to run into the wellbore formed from the terranean surface to the one or more subterranean formations, the second whipstock comprising:
a second bore of a second diameter that extends from an uphole, angled face of the second whipstock to a downhole face of the second whipstock, where the first diameter is the same or substantially the same as the second diameter, and
one or more second keys formed on a radial exterior surface of the second whipstock and configured to secure into one or more second keyholes formed in the casing to position the second whipstock adjacent a second lateral formed from a second lateral window in the casing;

an intervention tool configured to selectively pass through one or both of the first or second bores and enter at least one of the first lateral, the second lateral, or another lateral downhole of the first and second laterals; and
an adjustable entry tool configured to adjust between a closed position to pass into the first bore and prevent passage of the intervention tool through the first bore, and an open position, based on a signal from the terranean surface, to allow passage of the intervention tool through the first bore while the entry tool is positioned in the first bore.
