If your Baldwin lock is currently using a Kwikset key, it’s likely part of the Baldwin Prestige series, which uses SmartKey® technology and is compatible with Kwikset (KW1) or SC1 keyways. That means yes—you can buy a Baldwin-branded key, but it must match the same keyway your lock is using. Here’s the catch: if your lock is keyed to a Kwikset KW1 keyway, a standard Baldwin Estate key (which uses a C-keyway) won’t work unless the cylinder is swapped or rekeyed. However, if your lock uses the SC1 keyway, you can use any SC1-compatible key, including some Baldwin keys.
