Cadillac SRX Key & Key Fob Replacement FAQ

How much does a Cadillac SRX key replacement cost?

The cost of a Cadillac SRX key replacement varies depending on the key type and year model. Standard transponder keys typically range from $150-$220, while smart key fobs with proximity can range from $250-$400. VATS resistor keys for older models are typically $80-$120. S.A. Locksmith & Security offers competitive pricing — call (210) 348-3677 for an exact quote.

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

Yes! S.A. Locksmith & Security specializes in all-keys-lost situations for the Cadillac SRX. 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 SRX key?

Most Cadillac SRX 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 SRX 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 SRX use?

Cadillac SRX 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.
