Can you program a new key for my Cadillac DeVille if I lost all keys?

Yes! S.A. Locksmith & Security specializes in all-keys-lost situations for the Cadillac DeVille. Our technicians can program new keys from scratch using advanced diagnostic equipment, bypassing the need for a dealer visit. We handle VATS, Passkey III, PK3+, and GM proximity systems used in Cadillac vehicles.

How long does it take to replace a Cadillac DeVille key?

Most Cadillac DeVille key replacements take 30-60 minutes depending on the key system. Standard VATS and transponder keys are typically faster, while proximity smart key fobs may take slightly longer due to programming requirements. We offer mobile service throughout San Antonio.

Do I need to go to the Cadillac dealer for a key replacement?

No! S.A. Locksmith & Security can handle all Cadillac DeVille key services — often at 30-50% lower cost than the dealership with faster turnaround. We have the same GM programming capabilities as the dealer for VATS, Passkey III, PK3+, and proximity smart key systems.

What immobilizer system does my Cadillac DeVille use?

Cadillac DeVille vehicles use GM anti-theft systems depending on the year model. These include VATS (resistor pellet key), Passkey III/PK3+ (transponder-based with Philips 46/Megamos 48 chips), and GM Proximity (smart key with Hitag 2/3 transponders). Our technicians can identify your exact system and provide the correct key solution.
