How to Master Keyholes on the PAT: Step-by-Step Strategy for Success
Boost Your DAT Score by Dominating the Toughest PAT Subsection
Struggling with Keyholes on the PAT section of the DAT? Learn a step-by-step strategy to master this tricky section, improve accuracy, and boost your score fast.
The Keyholes section of the Perceptual Ability Test (PAT) is one of the most challenging parts of the DAT for many pre-dental students. It tests your ability to analyze 3D objects and determine which 2D opening (or "keyhole") they can pass through—without rotating or scaling the object.
Sound difficult? It is—unless you know how to break it down with strategy.
In this guide, we’ll cover:

🔍 What Are Keyholes on the PAT?
In the Keyholes section, you’re given a 3D object and five 2D shapes. Your task is to determine which of the shapes represents an opening the object could pass through—without turning or manipulating it.
There are 15 Keyhole questions on the DAT, and each one is timed—so strategy matters.
🎯 What Keyholes Are REALLY Testing
Spatial visualization
Proportional reasoning
Attention to detail
Ability to mentally align views without rotation
Dental schools care about these skills because they reflect how well you'll navigate tight spaces, fine motor tasks, and 3D anatomy in clinical dentistry.
❌ Common Mistakes Students Make
Before jumping into strategy, avoid these rookie errors:
Rotating the object in your head – The test assumes a fixed orientation.
Ignoring depth and angles – Many students focus only on the outline.
Rushing through answer choices – Careful comparison is key.
Getting overwhelmed by surface details – Focus on overall shape, dimensions, and projections.
✅ Step-by-Step Strategy to Master Keyholes
Here’s a 5-step method top scorers use to dominate this section:
Step 1: Identify the Viewpoint
The object is always positioned in a fixed orientation.
Imagine looking at it straight-on, with no tilting or turning.
Focus on the front-facing projection and the surrounding depth features.
Step 2: Scan for Major Features
Look for distinctive protrusions, holes, indentations, or slopes.
Ask yourself: What parts of this object might hit the walls of a hole?
Step 3: Eliminate Impossible Answers
Rule out answer choices that are:
Too small to fit the object
Missing key projections
Incorrectly shaped (e.g., sharp edges vs. rounded ones)
Even eliminating two choices gives you a huge advantage.
Step 4: Match Proportions and Relative Angles
Compare how far different parts of the object extend.
Pay attention to angle sharpness, symmetry, and alignment.
Step 5: Make a Confident Final Choice
If torn between two, pick the one that includes every necessary detail—even if the shape feels a little “off.”
Trust your process and move on quickly.
🧠 Pro Tips for Keyhole Mastery
Practice with real-world objects – Try fitting blocks into different openings or sketching side views.
Use process of elimination aggressively – This section rewards test-takers who can rule out bad answers fast.
Time yourself regularly – 15 questions in 15 minutes = 1 minute per question max.
Review incorrect questions weekly – Learn what threw you off and how to correct it next time.
